Spyder's use the H3 bulb. H4 has the high low beam. Can-am uses a deflector to lower the light. HID's actually use less voltage once they are up and running. Found this out when installed on the Hraley. There is a bit of modification to the factory case. Not a big deal, just pay close attention to what your doing and all goes well. I bought Xenon HID's for $95.00 and was done in about 2 hrs. Mainly taking it down to get to it is the time frame...Just make sure you purchase the 1 with the compact ballast, you'll the the room to "CRAMMM" it all in there..J/K. you have room if you arrange accordingly..
Good luck if you go this route. I was pleased with the final result..
