Our 2003 Yukon has what seems to be 4 different sets of white front lights.

1) DRL's, below the lows and highs when looking at the truck
2) Lows (9006's, right?)
3) Highs (9005's, right?)
4) Fogs (no idea what rating)

I have a two part question, can I put 9005's in the low beams without absolutely blinding traffic? I've done it before on other cars (just have to modify the base a little bit) and it was perfect.

Also, is there an easy headlight / wiring mod that will let ALL FOUR of these sets stay on when the brights are on? Right now my 'flash to pass' enables the brights with lows briefly, but when you click the stem to full brights the fogs and lows go off.

I'd love to have just a little bit more light on these dark country roads around here...

 

the 9005s wont fit in the low beam spot...the opening isn't big enough...or maybe it's the other way around....maybe it's to big....i don't remember but it wont work.

 

Some of my other cars ran the same low beam high beam combo as our Yukon. You could install the highs in the low beam location by shaving off a little tab on the light before installing it - I'm guessing it would work the same here??

 

Summit and Autozone both sell the kit to turn all 4 headlights on...it is like $19.95 from both places

 

The late models use a different relay,summits are $37 (in that range)

 

Just went out and installed 9005's in the low beams and the high beams. There are two very small tabs inside the plug area, just shave those off and they slide right in.

 

Awesome little write up on the quad beam mod.

Along with one that I created when I had some questions.

does anybody know if you have to upgrade your wiring for higher wattage bulbs. i know they sell a kit for it but is it necessary?

 

Gray,

I hear from some diesel guys that the new wiring kits work great. www.kennedydiesel.com sells them, very high quality product.
