Flaming is overrated.
www.thelapd.com sells a DOT approved kit but it's not bi-xenon.
www.hidtech.com
www.brightheadlights.com
Those two companies both sell HID kits that are bi-xenon. I can tell you that brightheadlights.com is not a fly by night as I ordered from them about 2 years ago and had a good experience.
I haven't ordered from hidtech but they were very responsive when questioning them.
