A couple of notes for those considering HID headlight
1. You must have the crystal cut headlight vs the faceted stock headlight.
HID's reflect off the back of the crystal cut rather than project through the faceted face of the headlight.
If you try a HID conversiopn with a faceted headlight you will not be happy with the resulting light pattern since it will just sort of scatter.
2. A few have considered buying the HID kits for automobiles and just using half or splitting it between two bikes. We tried this and the ballast went out. Seems the motorcycle ballast is built a little different to withstand the vibrations that occur more so with a motorcycle.
3. We picked up our kits on Ebay for about $100-$150
