Kensun HID Kit

Not familiar with this brand, but be aware that single bulb HID setups can be a problem in single headlight systems such as the Rebel's. When the HID bulb eventually blows, you have zero light. Not so much of an issue in the daytime, but a real safety problem at night, particularly at speed in a curve!

There used to be an ebay seller that offered a motorcycle specific HID system. It had a two bulb setup (xenon low beam, HID high beam). IIRC, the seller claimed the bulb(s) were less subject to vibration failure than automobile systems. A dual headlight system sold for $45 and could be split into two single headlights. I haven't seen them advertised for a while, but then again I haven't looked.
