DRLs on with Parking Lights. It works. (Pics)

[NSXTC]

Cost...<$1.00

Jump the #86 term from the parking light relay to #85 of the DRL relay. (Actually, the schematic is wrong and if you look at the bottom of the DRL relay it's actually #86. Doesn't matter anyway for this application).

Here's the pic of the jumper...Only draw back is unless you use another relay, your parking lights will be on when your DRLs are on and vice versa. Going the later route will be more involved.

The relays are a pain to lift. Use a flat blade screwdriver and GENTLY pry lose. Strip both ends of a wire and insert into terminals. Push in relay to hold in place.

#86/85 are low current terminals so you don't really need a really thick guage wire. Get one about 1/8" or so.

Pics with lights...

[JCJ]

NSXTC, wow,
Looking good.
But do you mean that this way the parking lights and DRLs can and must only be on simultaneously? Driving by day AND night?
Solution would be then to turn off both during daylight. Especially where I live, because I get flashed often during the day by people who think I left my lights on unknowingly...
Thanks,

Already done. It occurs to me that I never use the parking light setting anyway, only the auto function. Forgot, I've got the Bosch off road lamps, too. I get so many people flashing me now thinking my brights are on. This'll be fun.

[NSXTC]

Yep. The parking lights and DRL will be on at the same time. Your right JCJ, you can simply turn off the DRLs in the daytime.

Forgot to mention that before removing the relays, pull the parking light and drl fuses (circled in red below) to prevent potential shorts caused by the flat blade screwdriver.

Once the jumper has been installed, put the fuses and relays back, but don't fully seat it until after verifying that the lights work. This way, it won't be too much of a pain removing the relays again.

alright boys....

let me get this straight....

in auto function I will still have the DRLs?
in parkinglgts I will have just parking,DRLs and perimeter lighting??

in "on" all lights will be on?????

Is this right and if so...please tell me this is something that Hummer Girl can do????

If you can pry open a can of paint with a flat blade, you can do this. The hard part may be stripping the wires. That's the extend of the difficulty.

You are correct on all of the above questions.

Auto - Parking lights with DRLs during day. At night, DRLs, parking and head lights. You can also turn off the DRLs during the day which will also turn off the parking lights.

Parking - Parking lights with DRLs.

On - All lights

Perimeter lights - DRLs, parking, reverse lights

"Parking lights" being the front orange lights?
"Perimeter lights" being the combination of lights you can program to switch on when using keyless entry and remaining on when exiting for a certain amount of time?

Parking lights are all the x-mas tree lights (i.e., front, rear, and running lights)

Perimeter lights are the DRL and reverse lights which you program using keyless.

The first thing was recognizing there are relays for DRLs and parking lights (this saved us a lot of time and $$). Next is to use a volt meter to find which terminal turns the parking relays on. Finally, use that same signal to power the DRL relay.

The tricky part was that the schematic is wrong for the DRLs. #86 is actually used for both relays, but the schematics listed the DRL as #85. I did this w/o the volt meter, but couldn't getting it working correctly. Only by using the volt meter was I able to find out where the problem was.

Thanks NSXTC, My light project was finished 12/7/3. I went with the relay kit from RICKS that you suggested.($34.00) I hired a shop to help with the wiring because of my lack of knowledge and it took a while because they had never seen an H2 before. Anyway, I have the fexibility switching the DRL's on or off at anytime with the switch. It may not be a lot of light, but it helps and LOOKS good. Thank you..AL

Very clear and easy instructions. Great job. Even I figured it out as soon as I opened the fuse box. I stopped the task at the last minute because I wanted to think through 1/ if I want all the X'mas lights on during day driving, 2/ I can no longer use parking lites for longer period because DRL will be on too. 3/ other issues related specifically to my Hummer and usage.

B Moore, what do you mean: "I went with the relay kit from RICKS that you suggested.($34.00)" I read through NSXTC's posts several times but did not find such suggestion anywhere.

OK everyone, here's the cat's meow. I placed a diode, purchased at RadioShack, in line with the same wiring connection shown in the previous pictures posted by NSXTC. The diode allows current to flow only in one direction. Now my DRLs turn on with the parking lights, but the parking lights stay off during daylight hours. I checked the current across this connection with my voltmeter and it measures only 125mA, that's 0.125 Amps. I used a 200V 1A Silicon Diode from RadioShack (part No. 276-1102 "1N4003 Micromini Silicon Diode") and soldered it to the 20g wire I used. Covered the connections with heat shrink tubing. The diode only works in one direction, put it on backwards and it won't work. We'll see how long it lasts. http://www.elcova.com/infopop/emoticons/icon_smile.gif

Nice touch Mango.

Actually where I live, having running lights on (meaning the rear brake lights as well) makes me more visible in morning/dusk fog where the sensor does not trigger the headlights. Also great for short tunnel pass.

Anyone know why there are 2 filaments in the DRL's?....I only get one light level...the lower one. How do we get the brighter one to light up?

To JCJ:

That would work if the bulb does not have offset guides, which most 2 element bulbs have so you can only stick them in one way.

[Mango]

I think the cathode side (side with bar marking) faces the parking light relay. Just turn on your headlights the make the connections temporarily and see what happens. When connected correctly, you can hear the DRL relay click on. Be careful not to let any exposed ends of your wires ground on anything!

This discussion group is really the best. http://www.elcova.com/infopop/emoticons/icon_biggrin.gif

I already installed the jumper and will be getting the diode installed as soon as I get one.

Did anyone test the current (amps) on the DLR and xmas trees? The 1n4003 is only a 1Amp diode.

Just to make sure....I'll be putting in a 6amp 50 volt diode from www.mouser.com (http://www.mouser.com) part# 583-6A05

[Mango]

Glenn, since we are crossing the switch side of the relay instead of the actual high current side, the current is very low. As I stated in my previous post, the current across the bridge between the 86 leads on the parking light and DRL relays is less than 1/3 of an amp. I used a 1 amp diode and mine is working fine.

I am beginning to think about replacing the DRLs with a fog light like the PIAA 540s. Mounting these is going to be the problem. I'm going to start a new thread on this topic.

"They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."

[JohnnyBoy]

I like the mod NSXTC has come up with but have one concern. Basically the DRL's will be like fog lights, meaning they can be on at night while your regular lighting is on. Where I live it is illegal to have fog lights on when your high beams are switched on. Example being in my wifes BMW when the fog lights and headlights are on while driving around and you turn on you high beams, the fog lights automatically turn off.

You should be able to do something similar to everyone else, except.....

Run the jumper with diode from the DLR relay to the headlamp low relay. (instead of from the parking lamps.)

connect the diode so that current is blocked from the DLR to the HDLP-LOW, but it allowed the other direction.

[Mango]

I measured the current from the 86 lead on the parking light relay to the 86 lead on the DRL relay with the parking lights and thus the DRLs activated. Diode was not in line yet.

PhilD, Have a little faith. I aced physics in college http://www.elcova.com/infopop/emoticons/icon_smile.gif. Only way to measure current is to have the voltmeter make the connection. When the voltmeter made contact, the DRLs turned on and the current measured was 125 mA. Took the probes off and the DRLs turned off. No other connection was present in parallel. Promise.

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> so I'm not sure why you are getting the 125mA reading, as the DRL's draw more than that, unless GM have found a way to defy Ohms Law.
<HR></BLOCKQUOTE>

Phil...

Ohm's Law still applies, even for GM, as well as other rules for parallel circuits. http://www.elcova.com/infopop/emoticons/icon_biggrin.gif

After the 10A fuse the DRL circuit becomes a parallel circuit with one circuit through the relay contacts through the bulb filaments to G100 ground. The other circuit goes through the relay coil to ground through the DRL control of the BCM or through the added diode to the Park Light control of the BCM, so actually the diode only carries 125mA of the total load.

The BCM could not handle the 54W load of the filaments, the reason for the relays, and the added diode becomes a one way street for the DRL relay coil to seek an additional ground when the park light circuit has continuity.

Made this mod in about 2 minutes, took longer to look up the wire. This is such a great idea. I hope everyone will share these ideas like this as it is just a little gem. I'm making a small personal note book off the ideas so i can always refer back on next rig. I used a real light gage wire. I think it was about 20 gage. Do You think that will be heavy enough. Has anyone experemented with wire size? I have not put diode in yet I'm watching to see if while driving around it gets others to take more notice so as to prevent someone from smashing into Me. I have always been a defensive driver but it is all the others I worry about on the road.
I'm wondering and it is not really all that important but I'm assuming a person would want to keep more replacement bulbs around as the increased time of the different bulbs being on when normally they would be off will upset how long they were supposed to last. This thought just came to Me as some of the billet trim like roof top marker billet is held on by 3M double side tape so the more often they need replaced then tape needs replaced. Where can I buy that 3M tape that is used in alot of the mods on H2? Your info will be appreciated. Also do You think the bulb life will shorten all that much as I mentioned?
Thanks

While I did the diode mod a couple months ago, and it works just fine, exactly like it is supposed to, the one thing I didn't like was the loss of the ability to run with only the parking lights on. By the way, to confirm what has already been mentioned, a small diode is all that is needed. The current draw for the relay, used to turn on the DRLs, is only 150 ma (0.15 amp).

To have no DRLs with the parking lights, is something that I still wanted when I go cruising in the Christmas Lane area of town (hundreds of houses lit up, and people cruise through without their headlights on – very holidayific!). The DRLs being on would be pretty annoying.

When I installed the diode, a while back, I used a "wire nut" (a little twisty thing that you put over the bare wires to tighten the two wires together. I figured that if ever I wanted to revert back to the original working all I needed to do was untwist the wire nut.

Yeah, that works, of course, but I wanted a cleaner solution. So, since I was under the hood to wire in some other accessory, I decided to bring the wires out for the DRL mod. It is a simple switch that I mounted on the dash, directly in series with those two wires.

Switch on (contacts bridged) and the mod is in place, giving me the DRLs on with the headlights.

Switch off (contacts open) and the action is like original. Thus I can have just the parking lights on (no DRLs).

AL MOORE had mentioned this a while back, but I only thought I’d resurrect the subject, to remind people that you can have both modes, with a simple switch. (Bringing the wires through the firewall was the HARD part, but I was already doing that for the other wiring I was doing anyway.)

Hummm, connecting to the headlights...
Yes, that will give the usually preferred and cool (IMHO2) look of the forward four white lights on all at the same time, and you can still have the parking lights alone.

Good, but I still have the option to have the parking lights and the DRLs and not the headlights (not often, in reality).

I do like having the option, but if I were to want the DRLs+Headlights then your method would be an easy way, and no wires going through the firewall, too (what a chore). Thanks!

Hey Doc,
So does that mean durring the day when your DRls are on your parking lights are not on as well? And at night when you throw on (or when it auto switches) the headlights the DRls automaticaly stay illuminated? If so I think thats what I would want. How is that done again?

[JMV1210]

Just connect along the yellow line there. You should also throw in the relay so the drl's don't turn on the headlights in the day...

This may be it????

That's relay, spelled D-I-O-D-E.

Hey, I work with body parts, not electrical stuff http://www.elcova.com/infopop/emoticons/icon_smile.gif (my brother-in-law laughs at me everytime we're building/working on something...can't even get the tool names right...). Yes, it's a diode. It's from radioshack...I know the part number is listed somewhere here on the site, might actually be in this thread... If you can't find it, let me know...actually, let the members know, they'll direct you.... http://www.elcova.com/infopop/emoticons/icon_wink.gif It only cost about $1.

And, yes, you're right. During the day, the DRL's are on only. At night, when the headlights turn on, the drl's stay on. They pretty much run night/day... I don't have the option of turning on the DRL's on without the headlights though, which is what the other connection will accomplish.

Hello Everyone

If I like to have the DRL lights on only at high beam, how do I do the wiring then??

rgds

Tomas

[Jimstepside]

I like the look of the DRLs on with the headlights, but not the park lights. Why can't you jumper the headlight relay instead of the park light relay?

[ChuckE]

You can jumper it to any relay you like, even the horn relay if you want http://www.elcova.com/infopop/emoticons/icon_eek.gif. Just use a diode instead of only a wire, that way you don't get any reverse action of the DRLs also turning on the "whatever relay".

[VTSTOMPER]

I think I might go pick me up a diode baby!

I will do this tomorrow! I think I will be doing the low beam and DRL combo! http://www.elcova.com/infopop/emoticons/icon_smile.gif

Hello everyone

I tried to get the DRL:s on at high beam only like this (only the blue line) but that was wrong. Anyone knows how to do it?

This should work. I currently have my drl's on with headlights-low. You could easily switch that to Highbeams....with the blue line. I guess I may try using a line to the highbeams along with the low beams, so they don't shut off with high.... I haven't tried the blue line yet, so let me know if it doesn't work...

DOCHUMMER,

I want to have my DRLs on during the day and at night with my low beams. I don't want the parking lights on during the day only at night.

SHOULD I:

Jumper the drl and low beam relays as shown above in yellow only? No other connections?

Also which way does the stripe on the diode face towards the drl relay or the low beam realy?

THANKS...this is a great mod!!!

[dochummer]

By doing this with a wire rather than diode, does the low beam remains on with DRL also at all times in "auto" light setting during day and night?

[dochummer]

Yes. The wire will allow the current to flow both ways so the drls will also activate the headlights during the day. The diode is pretty cheap...I think less than a buck for two.

I think the side with the mark faces towards the DRL relay. I can't see the mark anymore d.t. the way I've set it up.

Here's the relay: RadioShack (part No. 276-1102 "1N4003 Micromini Silicon Diode")

[Sportsdude]

Dochummer, Sir Thank you.

[Sportsdude]

Anyone have problem with DIC saying "turn signal on" after doing this mod? Mine comes on when I did this mod. I have the DRL come on with low headlights.

[dochummer]

nope. Checked the jumper settings?

[Humdingah]

I decided to do this to my truck the other night and, while I had the soldering iron out, I made a total of three jumper wires with diodes. I obviously only need one of these so the first two people to PM me with their address will each get one. The diodes are soldered to black wire on the 'feed' side (the side that goes to the parking light, low or high-beam relay) and red on the side that goes to the DRL relay. They're heat-shrinked and long enough to allow you to attach to any of the three aforementioned 'feed' relays...just cut to size and be on your way.

[tomp]

I think I am going to have my DRLs wired to a switch so I can trun them on at any time.

For those interested, I have seen the DRL bulbs available in yellow so they can be used as fog lamps.

[DeBest]

Alright, I have just read the last 5 pages of updates and I am more confussed than when I started. If someone can summerize what I need to do I would really appreciate it. I have an 06 that I just want to add the DRL to the auto function for use with the Headlights. During the day I would like them to opperate as they do normally without any additional lights or markers on. Lastly can anyone tell me what they would reccomend if I want to upgrade to a brighter DRL and Headlamp without the cost of the HID's. What DRL bulb would compliment the Silverstar Headlamps?

[DeBest]

CAUTION CAUTION CAUTION, I tried the jumber today on a 06 H2 exactley as outlined with the jumper and the diode. Worked for about 30 seconds and then it started spitting and sputtering and stopped running. Tried restarting it several times had to have it towed into Hummer they said that it has fried the ECM. This vehicle only has 380 miles on it. They will not warranty it, I ll know tommorrow what it is going to cost. Has anyone had anything like this happen. HELP!!!

[Fastest H-Town Realtor]

Bummer about the fried electro-BBQ. Methinks you did not do it correctly, unless AMGen redid the box. Even then, the schematic should have shown you the correct slots.

[DeBest]

Does anyone know if the Fuse box did indeed change from 05 to 06?

[Aubs]

No idea on the fuse box, sorry to hear about that though. I just tried this mod, and it worked successfully. The one wire keeps the DRL's on at all times, even with High beams. Now, I just have to get some serious DRL bulbs and get rid of the sissy stock ones!

Mark,
Thank you for the price on the ECM, can you find out how many hours the book calls for the replacement of the modual I am trying to get a total price. This way I will be much better prepared when I talk to the dealer on Thursday.

Thanks Again!!!

[dochummer]

Ok, I haven't actually replaced the pcm in an H2 before...but it's not that hard is it? I've replaced pcm's on other vehicles and it was a matter of disconnecting cables, and swapping it out....

[OrangeCrush]

I'll check tomorrow but I honestly can't see it taking very long. Most ecm's only take a few minutes to replace. Sometimes you may have to remove some bracketry/battery/brace to get to it but I couldn't fathom it costing more than an hours labor.

However, I will check tomorrow.

Mark

[DeBest]

I was told that the ECM on a 06 H2 is up under the dash behind the instument panel and that it is quite involved to get to it. I was told that the whole dash practically has to come off to get to it. I hope someone can tell me exactly where it is and how many hours the book calls for to replace it.

[dochummer]

If it's not covered under warranty...are they going to cover it after they replace it?

[OrangeCrush]

I will get the GM labor rate tomorrow and let you know unless someone mentions it first here.

[DeBest]

Is there a right and wrong direction to install the diode. I picked up a diode from Radio Shack yesterday and I want to try the install using the diode this time. The diode has a thin band on one end of the barrel is that the front or the backside of the diode. Can the thin wire coming off of each direction of the diode be cut to shorten the length of the diode without effecting the diode? By the time I add the jumper wire it will be much to long if it can not be cut.

[dochummer]

I cut mine with no problem. I don't remember in which direction the band is supposed to go..but I know that you want the current to run from the headlamp low to the drl...or whatever your setup is...and not the other way. Search back in this same thread and there should be a post that tells you which way is which...

I installed mine with the striped end of the diode towards the headlamp (I wanted my drl's on with the headlamps) Not towards the DRL relay.

I installed it backwards at first and nothing happened. I switched it and it worked fine.

Dochummer, did you place the diode on the red lead or the yellow that you added?

[HummBob]

FINALLY installed the jumper today with diode!

One question though, maybe someone can help, I want the the DRL's to stay on when the headlights/parking lights go on auto at night, but I DON'T want the headlights/parking lights on during the day. So I jumped #85 on the DRL and #85 on the HDLP-LOW, but I got all of the lights on during the day?

Please tell me what I'm doing wrong!

[DeBest]

I am interested in hearing the answer to HummBob's question also!!!

[H2Finally]

Prob reversed diode. Before you turn it around and plug it back, do QUADRUPLE check that you're jumping only trigger to trigger between the 2 relays.

[dochummer]

Yeah, you probably reversed it. Maybe you should post a pic of your setup just to make sure you've got it right. http://www.elcova.com/infopop/emoticons/icon_smile.gif

[HummBob]

http://host.jwcinc.net/1869992/fuse.jpg
Kinda hard to see but I have it jumped from DRL #85 to HDLP LOW #85. I tried switching it around, and nothing happened. Maybe the diode is bad?

[DeBest]

Originally posted by dochummer:

DocHummer does HummBob's post above look right for the DRL's to stay on with the Headlights and have everything else operate the same as factory. I see that HummBob is from Canada I have heard that there are some differences in electrical setup for Canadian VS USA manufactured H2 units.I am being cautious since I have already had a bad experience that I do not want to repeat.

[DeBest]

Can someone summarize the above posts and let me know if I need to run one jumper from the DRL's to the PARKING LIGHTS and another one from the DRL's to the HEADLIGHTS LOW BEAM if all I am trying to achieve is to be able to run the DRL's with the LOW BEAMS at night or do I run just one from the DRL's to the LOW BEAM???

[HummBob]

DeBest,

The way I have it works properly. I'm just an IDIOT. I did the jumper in my garage DURING the day, so I assumed it was light enough out. But my auto lights came on in the garage.
Took it outside, it works properly http://www.elcova.com/infopop/emoticons/icon_rolleyes.gif

HummBob can you tell me what the results are of your jumper the way you have it in the above post. Do you still have the DRL's on during the day? What lights are on when you turn your headlight selector from auto to the parking lights?

[Sportsdude]

Is it safe to put a diode from high beam to low beam relay? Just curious when high beam is in use, can the low be on also?

[zeros]

i did it on my chevy avalanche and it worked great.. i havent tried it on the hummer yet.. but i would think it would work the same!

[Hummie2]

Originally posted by Sportsdude:

NO! Never illuminate both filaments in single bulb headlamps. It overheats the bulb and housing. I have been told it can cause bulb to burst although I have never seen it happen. If the headlamps had seperate high/low bulbs as in dual headlights on old Chev P/U you can do it on them.

BTW... DRL Relay to Low Headlamp Relay jumper w/diode works great. My truck has been that way 3+ years.

[Sportsdude]

Ok, thanks. I was curious if anyone have tried the hi/lo mod.

I don't know if there is way to turn off the DRL's during the day. Safety feature.

[zeros]

here is what i did.. face the side of the diode with the line no it toward the parking light relay..

[zeros]

here is a pic

[Aubs]

I think you just turn the headlights switch to the round circle position (left) and then it will bounce back and the DRL's should be off until you restart the vehicle.

[The Ledge]

Thank you all for these great DRL mods.

As mentioned below by NSXTC regarding removal of fuses for the DRL and Parking Lights mod, if I will be doing the DRL mod with the low beam headlamps, then I should instead remove those fuses marked "LO HDLP-RT" and "LO HDLP LT" with the DRL fuse? Thanks, just want to make sure.


Forgot to mention that before removing the relays, pull the parking light and drl fuses (circled in red below) to prevent potential shorts caused by the flat blade screwdriver.

Once the jumper has been installed, put the fuses and relays back, but don't fully seat it until after verifying that the lights work. This way, it won't be too much of a pain removing the relays again.

[This message was edited by NSXTC on January 04, 2003 at 09:35 PM.]

[The Ledge]

Never mind! DRL to low beam lamp mod completed - another very satisfied H2 member! :)

[obzidian]

to.. much...technical...stuff...overload....!!!

why hasn't this thread been stickied. Its a commonly asked question and thge newbies, like myself, will have it for reference and not make a new thead.

just some thought!! :)

anyways, gonnat try this out tonight, will get back with some pics...

[obzidian]

well, that was easy. For the exception that its been raining all day today, i got it done.

Im kinda impatient and couldn't wait to get the mod done so i got my unbrella, parked it over the fuse box and blamo!!... No water hazard!! Well, still kinda dumb... Acutally, dont do what i do, last thing i need is someone do the same and get a short, thus blaming it on me or something.

ANYWAYS, truck looks great. Will have some pics up (keep saying that!!) I also got a set of 8K HID's as well and run the sylvania's Amber in the DRL's. Looks great! Those sylvania's shine really cool and are bright for a turn signal bulb.

so, here ya go for the dumbies like me, cliff notes!

Step 1: get some 20g wire, a 200v 1amp diode (Radio shack PN: 276-1102)

Step 2: Install the diode inbetween a line of wire. Or better put, get two pieces or wire and wire on to each side of the diode. You can solder it or wrap the wire around the diode wire and tape it up with electrical tape (NOT RECOMMEND, you should solder it)

Step 3: Remove the Prk fuse 10amp and the drl fuse 10amp.

Step 4: lift the park relay and drl relay and place the wire/diode ends (exposed wire... DUH!! :) ) into the specific slots in the relay. 86/85 respectivily. Make sure the little grey strip, the cathode side, is point towards the PRK RELAY 86. Also make sure the diodes wires arent exposed and not grounding on anything.

Step 5: Replace the relays in their specific slots. Make sure to line them up correctly; they got numbers next to the contact points on the bottom so its really easy no to mess this up.

Step 6: Replace the fuses.

Blamo!! your done! I did it with my light switch moved up to the main headlight setting not auto. So with your headlights on, you would be able to see the DRL's turn on when the connection is properly made. If not, take your time and re check everything. Check your wire/diode connections, etc.

Step 7: Enjoy!!

[HUMMERcustoms.com/TAZ]

I jumped with just wire becaused I wanted the running lights and drl to be on all the time day or night. The drl keeps runnings lights on in day and running lights keep drl on at night. No diode just wire.

I wanted running lights on all the time to make sure even though the rig is as big as a house they were seeing it with all lights possible to help aviod stupid drivers from missing seeing a house rolling down the road. Then at night the drl's just help see better under the low beams sort of like a fog light.

This should have been found in a search but, obzidian steps should be booked marked if you need to go back again.

[BGA23]

I just popped in the diode with the following configuration: DRL #85 to HDLP LOW #85 with the grey strip on the HDLP LOW side and both the DRL and low beams come on at night but the DRLs are off during the day. I'm not sure if I'm happy with this or if I want to keep them off but any thoughts why this happened?

Is this right,

During the day in Auto mode I have no lights at all.....In park, I have park and drl. But also if I turn to either park or all lights, then turn her off and open the door there is no beeping noise, telling me that I left the lights on????

Besides that it works great, love havin the drl's on at night!!

This thread is actually really old. If you look at the 1st page again, you can see the posts are from 2003. So they started modding the '03s and so on. The H3s are also referencing this mod. Again if the panel looks like the pics on the first page, it should be OK. Do not "accidentally" touch other connection points or you may short out your whole panel.

So for normal DLR's on during the day (and nothing else) and adding DLR's while the headlights are on (lowbeams) we jumper the relay's as stated on the first page of this thread and add a diode to go to the low beam head lamp relay correct?

[Diceman]

Just connect along the yellow line there. You should also throw in the relay so the drl's don't turn on the headlights in the day...


This is the one, Just the yellow or the read and yellow, but the yellow is a diode...

This is the one, Just the yellow or the read and yellow, but the yellow is a diode...

What he was mentioning was if you added another jumper (the yellow one), you can only have the DRL on when the low beams are on. No DRL when using High beams.

Just do the basic one first with diode. I think you'll be happy with just that one. Also, look at your H2 panel and you will realize how easy it is. I was scared to do it until I saw what I was dealing with.

Just an FYI, it works with the 07's.......

Nice easy mod with the diode!

I must have done something different. I pluged the DLR's into the running lights and they stay on no matter what beam i'm on.

Stuart,
I read this two times while on conversence call this afternoon and downloaded it after what you tried to do on my Hummer. It is important to me and thank you. I think we got it right. Why I really wanted to get this done is because Wyoming is 97,000 sq. miles and all the roads are "open range". You need all the light you can get at night. From White mountain, I am looking at the Unita Mountains 150 miles away in Uath. Between me and the mountains is the world famous Flaming Gorge Reservoir. 92 miles of trout fishing.
Thank you for looking out for the "fisherman".

easiest and coolest mod in the universe:dancingbanana::dancingbanana::jump:

[bobh002]

very cool mod.....except I put ambers in my drl's

[HumminNBoatin']

Just got done doing this mod, Very cool NOW onto my light bar with Brites!!

[guruerror]

Okay...I've been reading through this forum for about an hour and can't seem to find what I'm looking for...

I'd like to be able to maintain the original daytime functionality of my DRLs AND also have them stay on at night (when the headlights are on)...BUT...

...I do NOT want to wire them to the parking lights. I do NOT want to have my parking lights on during the day when my DRLs are on.

There is reference in an earlier post to a 'relay kit from RICKS'...? Does anyone have more info on this relay kit or another method to make this mod work?

Thanks in advance.

[guruerror]

Ya know what...I just found the post in this thread regarding the diode...nevermind. I guess I just needed to read for an hour and 5 minutes before opening my mouth.

Thanks anyway.

Hey I did it first :clapping: Exactly one year now and still working like brand new:beerchug:

[Bykw2]

If any one is interested I have a set of 3157 blue LED bulbs just for the DRL!

PM if interested!

[guruerror]

WORKS LIKE A CHARM!

The diode does the trick!

[csxmoose]

did mine at work today, 3 mins flat... and that includes the time it takes to open the hood and find the fuses and relays!:clapping:

i am a wire rigging god... just check my work... i don't charge much either, in case someone needs some help.....

Now that I've got another H2, I had to do this mod. For anyone interested, I made up 3 extra diodes wire strands.

For the first 3 people to PM me, I will send them the diode. It's soldered and heatshrinked, ready to go.

For some reason nobody around my area sells the 1 amp 200v in4003 diode the closest I found was the 1 amp 400v in4004 can I use this one or should I order the in4003 off of ebay

[MONSTERMATT]

U dont have radio shack???

[SteveGt]

Ya but for some reason in Toronto they only carry the 1 amp 50v diode

[SteveGt]

Does anybody know if the in4004 diode wil work its a 1 amp 400v

[splne1]

FINALLY decided to do the diode mod. Not to long ago I bought some 39 led DRL bulbs for the H2 and they match my HID kit pretty close. Ill post some pics up as soon as it gets a little darker.

[Tex_h2]

Here are my LED's DRL I bought from a place in Japan51340

I bought some on eBay TOO!!! The PIAA's I was using burnt out WAY TOO QUICK!!!

[SHANNHUMM]

Worked like a charm. I wish the rattle in the dashboard was as simple.

thanks,
Shan

Here are a couple of pics of the before & after!

AWESOME!

[The_Yeti]

Great thread brought back to life. I was wondering how people where doing both lights on. Now the question to myself is to Diode or not to Diode?

Whats the size or a description to ask the Radio Shack guy? edit: found it. Radio shack PN: 276-1102

[The_Yeti]

Ah did mine after work.. decided to go no diode, Washington pretty doom and gloom at this time of year.
Thanks!

[vandy0090]

hey guys quick question. i tried this out on the wifes truck.

with it in auto i have no light
in parking i have the drls and perimeter lights
in on i have all

anythoughts?:confused:

[alsalsa]

My rig same outcome as Vandy0090:

with it in auto i have no light
in parking i have the drls and perimeter lights

[Decade]

Double check your jumper wire and you are using the correct relays.

[pteam]

I've said this before but I guess not here. THIS WILL NOT ADD MORE LIGHT AT NIGHT! The DRLs add very very very little light, that very little amount will get drowned out by the headlights. This is more of a "look" mod. I did this mod before. Also there is a risk that this mod can cause problems with your fuse box as its happened to owners before. I also bought the cheap ebay LEDs to replace the bulb in there (don't do it). Neither does anything. The only thing that will add light is to take out the DRLs and put in HIDs in that housing. You can buy 4 inch HIDs off ebay that will fit perfectly in that hole and will almost double your light output.

do the 4" Hid's plug into the factory wiring?

Thanks

:perfect10s: Has anyone suffered anything serious from this mod. I think I only read one horror story

[twinmill28]

This was the first thing on did on my 07 H2 right after I bought it in March this year. Still working like a champ--no horror stories here.
This should have come from the factory set-up this way. I was adamant to get it done because my H3 was set up with a separate switch to turn the those lights on--the 2 should have been the same way.

[OrangeCrush]

:perfect10s: Has anyone suffered anything serious from this mod. I think I only read one horror story

Nope, I did this on my '03 many years ago and then on my '06. Now that I have the truck back from the conversion, I'm going down today and buy another diode and install it again.

It's worth the minute and buck you have to spend.

Can you plug the HID bulbs into the stock wiring?
or does it have to be rewired?

[NIK1]

Has anyone done this daylight driving light mod to a 09 H2.I traded a 08 H3 Alpha for the 09 H2 and like having the bottom lights on with the low beam headlight.Plus,whats a good replacement bulb to use for a differant look if any.
