I am pretty sure this one is the Cygolite and the larger of the two mounts is the Planet Bike Superflash. Took some time to work on this one this afternoon. It should work on most Cygolite blinkies (Hotshot Pro 80 USB, Hotshot 50 USB, Hotshot SL 30 USB)



Works exactly the same as Cygolite's original mounts except this allows you to mount on a GoPro mount, It should provide a few more mounting options. No additional hardware is required. I still have to clean up a few edges and verify all the dimensions are correct.

This will not fit the Micro or Hotrod models.
