the hid (high intensity discharge) lights only come in kits. my friend got it installed on his car and from what i can tell, there aren't any bulbs at all. seems to be just one large spark coming from parts attached to the housing. i could be wrong on this one, but that's what we came up with after reading your post. if you want the mercedes, audi, bmw headlight look, you're gonna have to buy that expencive *** kit. otherwise, you can just go with the bulbs that everyone else suggested. either way, keep us posted and let us know how it goes. good luck.
