Just installed the Harley Road Glide Bi-Xenon Professional HID KIT from SoCalMotoGear. HID both high and low beams. They sure light up the road. The hardest part was getting more wires to fit under the "hood". The ballast mounting was easy with the double sided tape, but cramming the other stuff (connectors) in was a chore. Couldn't find the hooks so had to remove the lights and hook the outer fairing on to make room for the back of the lights to fit, but it was worth the effort. I didn't want to tie wrap the wires inside because I needed enough wire length in case I have to remove the fairing again especially with my garage door opener and radar detector under there.
