This Topside helmet light mount allows you to mount your light to a smooth or urban style helmet where a rubber strap can’t be used. It comes with the GoPro style mount and a 3M adhesive sticky pad.

Simply remove the backing paper and stick the mount to your helmet, and then slide in the Topside clip.

Topside lights are sold separately.

The clip will take many other bike lights that are approx 25-30mm diameter.
