Not every 3157 will work. There are many types of 3157, with totally different bases. The 3157 used in Hummer has snap in base with 2 metal contacts on each side, some 3157 has only 1 wire each side, some 3157 has larger bulb as ours but some has tiny bulbs. I have switched to new 3157 "Super White" bulbs I found at Kragen Auto, these are the $7 cheap bulbs, light became white (vs. yellow) with a slight blue tint, the result is excellent.

In the topic: NEW BULBS. all 3 types of bulbs on the front were replaced and reported(with photo). http://www.elcova.com/groupee/forums?a=tpc&s=2826088551&f=6706011751&m=702606930 2

You can also easily do a search on eBay with 9007(head), 3157(DRL) or H3(fog). Some eBay sellers of bulbs are not professional and do not back up quality as promised, but the search result is very educational to understand the bulbs and prices. I saw 9007 head lamp Super white bulbs by GE at Wal-Mart for $19 a pair.

Has anyone installed any of the lights that produce a purpleish tint, like the ones on late model BMW's?

There's tons of discussions and posts and pictures on HID in the TECH sections, you have to do your homework to read through them. All your answers are in those posts.

Thanks, MAC...

I got the right bulbs and I also attatched the wire to allow DRL's to run with parking lights in the daytime and all to be on at night...the wire I used was a 12 gauge...very thick but worked...

PROBLEM: the new 3157 super cool blue bulb on the driver DRL blew after driving for a day...don't know if it was bec of too thick of a wire or cheap bulbs...HELP???

I also noticed the original bulbs had 4157 on them...are there bulbs with that #???

I'll go back to AUTOZONE and return the bulbs...if my orig DRL blows, then prob something wrong with the thick wire...

INPUTS please....

rpv, Same thing happened to my first pair of blue super white 3157 bulbs after 1-2 days. I exchanged a new pair. 2nd time I was extra careful not to put my fingers on the bulb, clean the bulb first, then use rubber gloves when touching the bulbs. The new pair works fine for 1-2 weeks now. Xenon gas bulbs have much higher temp., any oil you left on the bulb, including the minor stuff you cannot see will burn the bulbs very fast.

Stock DRL comes with 4157 which is same as 3157 but more durable, not easy to find, did not looked to be any brighter than regular 3157. My new super white 3157 are great, if they burn out in 6 months, I'll just get new ones, cheap $7 a pair bulbs don't bother me much. For sure I'm not going back to old yellow lights.

I replaced the orig 4157/3157 DRL's and the same drivers side blew...I finally pulled the connecting wire allowing the DRL to run along with the parking lights and headlights at night and bought another pair of super blue, this time taking care to use gloves....so far so good...after one week, if things are ok...I'll reattatch the 12 gauge wire and allow the DRLs to go on at night...hopefully they last and if not, anybody else experience this prob after placing the connecting wire???...maybe the gauge of my wire is too thick???

How about these "Angel Eyes" in place of DRLs?
Possible?

Just a personal preference that I do not want to alter the Hummer factory look much, while many others go out to change the look as much as they can. The Hummer fog lamps look just right with the Hummer logo lamp guards. The new fog lamp H3 bulbs now deliver very bright cold blue light, even brighter than head lamp which has DOT Xenon 9007 bulbs, next step is to go to not street legal 100W head lamp Xenon gas bulbs.

H3 bulb is for the fog lamp or off-road lamp, I'm getting lazy with long word "off-road lamp", in bulb sellers' term, they are generally called "fog lamp", never "off-road" lamp.
9007 is for head lamp, and DRL uses 3157.

Wal-Mart has a line of Super White auto bulbs made by GE, I saw 9007(head lamps), H3(off-road lamps), not sure about 3157. The bulbs are transparent, don't know about the light. You can always return them, unlike eBay.

Thanks for the info on fog/off-road lamps. I used to live in San Francisco, 1/2 of the City is in dense fog 1/2 the year, reg. head light is reflected and of course you never should use high beam in the fog, fog lamps especially the yellow ones are most effective in the fog. As such, your statement about fog vs off-road lamps is logical.

Which reminds me H2 does not have fog lamps, I never noticed it before. Based on my driving experience in many states and Europe, fog lamps are not decorations but very important safety equipment, there were times I could not see anything nor go anywhere without the fog lamps.

On eBay, the H3 bulbs are described as fog lamps, not as off-road lamps. My H3 bulbs came from eBay, maybe I have fog bulbs in my off-road lamps. Whatever, I like the bright blue light.
