PIAA Bracket on R1100RT
The finished product. The PIAAs are below the mirrors. They are in a fairly safe location. The are wide enough to give the "looks like car headlights" effect that some people think may enhance safety and visibility. As far as I can tell, the lights don't effect the bike driver's visual field (as lights mounted above the mirrors might).
I haven't tipped the bike onto its side to see what hits the ground first.
