I bought a set of USDM headlights, had the covers opened, and put LED strips on the inside, as well as HID lights. After selling my OEM headlights for $500.00, total cost was $750.00 for the retrofit HIDs and LEDs. These are HIDs not halogen with projectors. Just about the same cost as the German ones, and Yes, mine are no longer DOT approved either. If I had gone plane jane, costs after selling the OEMS would have been $500.00.
