Having done 2 sets of HID lights in the past, with reflectors, I wont be going down that road again.... If the HID bulb is not in a projector bulb its pointless. Looks very bright when in front of the bike, but the light beam is pathetic and you lose the ability to have high beams (The magnet ones with high beams are stupid) and some of them have a tiny xenon bulb thats as bright as a candle. I wouldn't do HID again.
