i have a 2002 a4 1.8t, my headlight assumbly was broken, so i was thinking at the same time i replace it, i want to upgrade it to hid. originally, i dont have hid in my car. just wanna ask you guys if i wanna have hid with 6k, what do i have to buy? hid kit? hid headlight assumbly with hit bulb? or hid projecter? and where should i get it? from ebay or where ever?
thank a lot~

 

Well if you want to do things right, you should buy a pair of Xenon headlight assemblys and try and find stock ballasts and bulbs. There are more people selling the xenon headlight assemblys over on Audizine.

Otherwise, you could just replace your headlight with a normal headlight assembly, then get a HID kit that is retrofitted (the base of the bulbs are changed in order to fit in a non-xenon housing).
