I have done the dual headlight mod, but different than every other one that I have read so far.
I didn't trust the stock light switch to be able to handle the amps that two or four headlamps that it would power.
I deceided to use relays.
I used one for the low beam and two for the high beam.
I took a new wire from the power block ontop of the battery box. I also grabbed a new ground.
I took this hot and ground to the high beam relay #1 (NO) and then took the factory high beam wire and also hooked it to the relay, and then hooked a new wire (to the left headlamp [which is a h4 moded to fit in the h7 holder]) and then also reconneted the original right high beam headlamp wire. Also, with this lead I connected the high beam relay #2 (NC leading to the low beam relay.)
I then hooked the output from the high beam relay #2 to the power in on the low beam relay (NO). I also daisy-chained the ground from the high beam relay (#1). I then hooked the factory low beam wire to this relay and hooked the other side of the factory low beam wire (headed to the left [port side] head lamp) and added another wire to the low beam of the right (starboard side) head lamp.
So in the end, I changed the left (port side) headlamp to a H4 (high/low beam) and used the factory added a high beam wire to the left side and a low beam wire to the right side. Used the factory wires to control the relays to actuly work the head lamps, so that I only have high beam OR low beam on at a time.
I noticed that I needed this, because I took my bike for about an hour ride with my high beams on (which would be all four head lamps on) and when I got back my bike wouldn't start and I had to charge it. It was then that I deceided to add the 3rd relay and only have a max of two head lamps on at a time.
I did remove the airbox, battery box, battery...etc...It wasn't much of a problem, and I LOVE the end !!!

I attached the schematic, but it looks awefull small, so here is a link to the full sized file.
