H.I.D need ballast?
I have spoken to a person from http://www.hidkits.com/ and he said Sylvania or Philips is the way to go.
Call them if you have any questions as I had a phone call for over 20 minutes and he just kept going on and on! I think I spoke to william? cant remember his name but he was extremely helpful.
He really helped me out a lot. Only thing is he has a strong accent so you might not understand every word he says.
