Unless you plan to mail order, here in winnipeg there aren't many choices for the blue headlight look. But I do know a place in winkler that sells the eurolites xenon bulbs. My buddy has them in his 95 monte, and they look really good, in fact we parked beside a bimmer with true HID and it looked almost identical. The bulbs are $30/ bulb I believe. Don't buy the coolblues, they have no blue color at all, but nice white light (my pref.). I installed 9006 high beam coolblues in my low beam sockets, and it's really bright, no blue, but really bright white. That along with my 885 fogs makes my lights actually quite good.

They give off a bluish/silvery color. If you send me an email I'll give you there link. By the way these bulbs are $76.00 for the lows/highs and are 80/100 watt. Very nice and not that cheap lookin' multi-color junk that you see out there too
