I got the 6000K for my fog lights. There are 2 types of the bulbs. Crystal White and Blue White.
Crystal White will give you more purple color. The blue white gives you more white color and little blue. I like Blue White better than Crystal White, but it depends on personal choice.
The website I bought this is at www.autolites.net
They don't have the D2R bulbs yet, but they have the 9006 for your 2002 TL fog lights.
I will order the 6000K D2R bulbs for my lowbeam lights from somewhere. I will let you know if you are interested in it later after I buy it.
