Hey I keep fprgetting to post this but here's where you can get inexpensive H.I.D. bike kits with slim ballasts for $70 for two bulb kit and $45 for a one bulb set up. Sorry that I kept forgetting, I found the bookmark while looking for something else... Oh and they come with a lifetime warranty and I know quite a few guys who use them without any known issues.

Oh yea and they sell a wire kit that will make your headlight power a relay and draw the actual H.I.D. power directly from the battery for you guys with older bikes.
