YOU MUST PAY ATTENTION: 1. D1S/R LED kit can ONLY be applied to D1S or D1R HID replacement, and NEVER be applied to D3S or D3R HID replacement, it will cause HID ballast burnt; 2. Turn on your car when both of LED headlights are well installed, NEITHER stay with one LED and one HID, NOR stay with one LED and one out of bulb; 3. Do not install the driver or CANBus box quite close to projector and block the moving angle of projector lens, or it will cause AFL error on dash.

Apply to headlamp assembly coming with either projector type or reflector type. In projector headlight assembly, the bulb lights up all the time, the high beam or low beam is controlled by projector other than bulb.

All D1S, D3S and D8S look closely similar but differ by specification, the obvious way to distinguish is checking the contact plug color, black is D1S, green is D3S and blue is D8S.
