Yellow!

Finally had a chance to change the lights

Painted fog glass with Krylon Yellow stained glass, clear lamin-x, and 3000k HIDs.

I hate you, I can't for the life of me to get HID's to work on my avantgarde model without the strobing/flickering. Reduced down to Piaa Ion yellow bulbs.

Sorry? Haha. Is that with the error cancelers? Probably don't need it but I put them in anyways just in case.

Knightmare69

Yea, I tried pretty much everything, cheap kits, expensive kits, cancelers, relay kit, still they flickered and strobed.

Sorry to bring up a thread from 3+ months ago but I was searching around for fog light info and got caught off guard when I was reading this thread. It seems that there is a lot of misinformation about light color and its ability to penetrate fog/practicality. I did a few Google searches and found a post on this topic from the US Dept of Education's Office of Science stating that yellow lights had no greater "fog cutting" ability than white. Apparently it is generally agreed upon by most experts that get asked about this that the use of yellow fog lights is merely just custom and style.

If you want some more info, just do a Google search or check out these links:

Sorry about bringing up a dead thread just to go "nerd mode" - but I felt that on a community such as this facts go a long way in making decisions for our cars and it's our responsibility to make sure we aren't perpetuating falsities.

Also, I completely get that most people have yellow fogs for the look - and IMHO they look really great. (I'll probably get some yellow ones for my car ) --I just wanted to point out that there is no performance gain by having yellow.

3000-3200'K for fogs work best because theoretically they give the best contrast in adverse weather conditions, especially if you live in a fog infested area. But if you do not live in a fog infested area and it's just a look you wish to achieve, I do prefer 4000'-6000'K myself.

This chart does not show fogs, but is a good illustration of Kelvin differences.

^^That makes sense, but I am by no means an expert nor have I done much searching on the contrast advantages.

Actually, I found this:

Now normally I wouldn't trust any study that was only performed on 15 test subjects, but it seems to be posted on a trustworthy site. This seems to support what you are referring to, so hopefully it does in fact help.

Tired of my yellow fogs. Might take them out and get 6000K for both headlights and fog lights. Now I painted my fog lights with krylon yellow stained glass. You guys think paint thinner/stripper will help get it off?

I have yellow fogs (Hoen Performance Rallye) and I love them.
I have a medium smoke tint film on the glass so that the fogs do not stand out so much when not lit.


They look great from the outside, very bright and vibrant yellow (sorry I don't have a photo of the fogs on).
From behind the wheel they are barely noticable as the Xenon headlights overpower them.


But I think in bad weather they do make a big difference in being visible to others.

Yea it should, years ago when nightshade first came out I had used it but didn't like it and used paint thinner to remove it. Just apply it to the rag and work it slowly off as opposed to applying the thinner straight onto the lens.
