The Sport Diver or Pro Diver dive lights can be used on a bicycle if you secure the battery case to the water bottle basket (shown below).

In this case, we used the Velcro straps that are included with the light. Either the J (5w/10w) or the B (10w/15w) versions will not over heat when used out of the water.

Note: The battery case has not been designed to take excessive vibration. It is not warranted against electrical failure due to impact (i.e. 20ft Gonzo Cliff Drops).
