Ok, Hang on a sec. Do you have a 99 STS? If so, there wasn't even an option for HID lighting.

So, you're just looking for Whiter/Bluer bulbs, correct?

If thats the case, you can get bulbs for much cheaper.

I would search on Ebay for "9006 bulb"

Some companies I've heard good things about:

PIAA
HELLA
SYLVANIA (OEM) -Search for Silver Stars
NOKYA (These would give you the bluest tint I believe)

Also luminicsbulbs.com have the bluest bulb that i could find for the 9006 if you check out their pure blue i think you should be satisfied and price is unbeatable
