I am running Hella Generation III Ballasts w/built in ignitor and Ballast covers. The bulbs I had on my stock headlights were 9006 rebased Phillips 4300K D2R bulbs. The wiring harness was an excellent quality by xenondepot. I purchased these brand new as set which included 2 new ballasts, ballasts covers and 9006 wiring harness and 2 4300K Phillips 9006 D2S bulbs for $299 from xenondepots ebay homestore..
My Hella Gen. III ballasts look like this under the cover..
and the Phillips 4300K D2R with the 9006 base (
i purchased them from here, they are CHEAP now from what I paid a year ago ) looked like this..

so totall I paid for the kit was $410...if you do it right with all the proper stuff like D2R bulbs and a good brand like Hella/Phillips..you will be ever so happy with you kit and always remember..
YOU GET WHAT YOU PAY FOR! please dont go cheap

then I'll hafta slap u at SZ..lol
also another note with the Phillips bulbs, when they are brand new, they will look yellowish but after a week they will turn normal 4300K..and then after 3-6 months depending on use, they will color shift meaning they will become a CRISP blue color which I can tell you looks very very sexy! it does not hinder performance however..
