Has anybody bought an HID conversion kit for their supra? I'm not talking about buying the bulbs that are blue or white or whatever. The real HID, with real HID bulbs and ballasts and the whole 9 yards. I've thought about doing it, but i'm not sure how much of a difference it would make. I've driven tons of cars with factory HID and it's outstanding lighting, but I'm unsure of conversion kits.
