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

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

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.

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.

HTH's,

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

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!

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

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.

Yeah, you probably reversed it. Maybe you should post a pic of your setup just to make sure you've got it right.

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?

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.

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???

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

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?

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?

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!

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.

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

hi i just did this ...and it works great...i used the diode ..so the parking lights arent on during the day... looks nice! thanks!
