my buddy has an audi tt and the light color is sick... what would be an equal hid? temp? to get that would equal that light color/output?? for an 05 tc

 

4300k. all factory HID's (acura,bmw,audi,lexus etc) run 4300k's but keep in mind im pretty sure the tt's have projectors which will make them look different to our with no projector.

4300k is the best light output/color temp without looking riced out. its pure white

 

Colors vary by manufacturing, but all pure white hids I've seen were 5-6k. 43's are yellow. They are the brightest but everytime I've seen them they were yellowish. I went with 6k in the lows and fogs, 5k in the highs

 

Yellow = 3000k. I have 4300k (oem from a Lexus made by Denso) and they are not yellow by any terms. They are also not that obnoxious "white" aka blue color. They look just like all other oem hids.

if it came from factory, it will be 4300k which it the whitest. I have an HID retro using OEM products, my 4300k is no where near yellow. Like BLUE said, 3000k = yellow, 4300k = white.

 

Additionally, anything "whiter" than 4300k is useless in the rain and snow. In fact even 4300k will benefit from standard halogen or 3k hid fog lights.
Even my Volvo which has oem hids sucks in foul weather with out its halogen fogs
