I'm considering getting yellow ion crystal bulbs to use as headlight. I know PIAA, Mtec, and eurolights.com make them in 9007. Does anyone have this kind of bulb installed anywhere on any car? How yellow is it? Whiter than Lexus fog maybe? Or too yellow to be a street legal headlight?

 

i've seen a couple cars driving around with those bulbs. they are definately yellow. they are basically the same color as your standard yellow fog light. in other words, its a deep yellow. i'm not sure if they are legal or not, but i've only seen about 3 cars so far, so i guess its not that popular.
