Dude, this topic is getting quite old now..search past post's and you should come across it. Oh well, I might as well tell you while I'm at it anyway. The best kit is Korean and it should cost you about Rs 14-16,000. Chinese is pretty alright too, but the damn thing can blow if you keep flickin it. The higher in the Kelvin range you go, the less brighter the light, however the more blue it becomes. I have it installed in a 2003 Gli high beam, and the light output is very nice. Only downside though, stings oncoming traffic! Hope this helps...DOHC RULES!
