Delta Fog lights vs. Driving lights

[LoJac963]

I'm tired of my nasty OEM DRL housings, half the reflector is burned away at the top. The LED towers I installed makes them look 1,000 times better but I want something that looks even better.

I plan to buy the non-HID Delta set and eventually retrofit in some HID's like PDX did.

However here are my questions:

-what is the difference between the fog light and driving light sets? I thought I read somewhere around here the driving lights are fluted glass while the fogs are smooth??

-do these lights directly install into the factor mounting holes or is there modification requred to the back of the bumper?

-says it comes with a stand alone harness and relay kit. So do these plug into the factory harness at all or is there cutting and splicing required??

-Fogs show an H3 bulb for the light source, is that the same for the driving lights?

That being said I don't mind modifying or doing electrical work obviously if you've seen my build thread. At the same time I like to keep the electrical as close to stock as possible in regards to the plugs, etc in case I ever want to reverse the mods.

Basically I want the Deltas to function exactly like the factory DRL's we have (with the DRL mod most of us have).

Thanks in advance, and pics if you've got'em!!
