I hard mounted the matching clip to the bike using (holed) strapping from the hardware store.

I also mount a 2nd unit on my left drop bar. the last 2 pictures show another drop bar strobe that I have since replaced with the 2nd picture showing my PB SF. sorry for the crummy cell phone pic. btw: I really like having 2 good strobes and I feel the one on the left drop bar helps get me some courtesy room from the passing cars.
