I'm ready to purchase HID and foglight bulbs for my 08 Polish Metal Grey TL base with navi. I was wondering if 6k or 8k has the best output. As for foglights should I get yellow or white color bulbs?

 

For the beat output, you definitely don't want 6-8k. The higherthe Kelvin rating the worse the output. For the beat output look for phillips 85122+, the best kelvin rating is going to be around 4300k.

These bulbs seem to be the best of both worlds. As bright if not a little brighter than the 85122+ according to the pics in the thread and and you get a blue color to the bulbs.

3000k has the best output.. if you're getting after market.. stick between 4300k - 6000k
