you might look at the 4" fuego lights from Baja designs. Run a driving light for high beam and a fog for low beam. You can get them in HID, and you can run just the lens assembly...pod style.
I have the clamps, F2R, and 2 ICO's from Charlie for use in Australia this summer. I may still go to a frame mount to keep the weight off of the bars but I will still use everything except for the bar clamps.
My intuition nearly makes up for my lack of good judgement.
