Since I'm getting ready to do this same upgrade, I think I'll add a rocker switch (next to the one for my LED driving lights) for the headlight. Seems easier to me than using a timed delay relay - maybe, maybe not. I'll letcha know.
Just ordered the head light kit from Cycle Gear (same as Dan); $65.38 out the door.
