From this forum, I've gathered that if your going to buy aftermarket headlamps, to go TYC or go home. I've been reading about TYC on their website, and they say not to use an HID setup. Why not? Would it hurt anything (other than the warranty) if I do anyways? I already have an HID setup. I don't want to get rid of it and go back to halogen. If I can't use them, does anybody know where I can get a set of projectors and still use my HID conversion? All help is appreciated.
