I'm on a bunch of other forums and some of the car guys have had great experiences with these HID kits. Very small ballast, cheap, and what seem to be great quality. The guys that have had them almost a year now have had no issues. There was one instance of a dead bulb on arrival, no prob, sent it back got 2 in return. When I was looking through the site I saw they have motorcycle kits so I figured I'd pass the info along here. I was looking to see if anyone else had posted about these but I didnt find anything.
