Review on Hanperal Motorcycle Waterproof Handlebar Headlight by Billy Berry

I bought a wiring harness to install auxiliary lighting but I didn't like the double sided tape mouse switch. I cut off the derailleur and put a waterproof derailleur in it that I was able to mount right next to the right handlebar. Since the steering wheel of my 2007 BMW R1200 GS is narrower, there was little space. Very happy with the red light indicating the auxiliary lights are on. It didn't rain, so I can't comment on the waterproofness, but judging by the looks there shouldn't be any issues.
