this is what I have, on a '97 tourer,
http://www.ddmtuning.com/Products/HIDBIKESINGLEHILODDM-35W-55W-Single-HiLo-Motorcycle-HID-Kitthe wire harness with kit has it's own relay and is wired direct from the battery, the stock bike wiring only fires the relay which then carries the load of the light instead of the switch and stock wiring.
"HiLo" what that isn't, means NOT brighter on hi beam, but a change in the angle of the bulb by an electro-magnet which makes the light shine further down the road.
What I ordered:
wattage, 35w bulb (55w too much)
bulb type, H4 HiLo
bulb color, 5000k (white light)
going down from 5000k color the light starts going yellow
going up from 5000k color the light gets blue
inside the headlight bucket, I removed the "mushroom thingy" in front of the bulb.
