Haven't used it at all on the bike. I have it for work. It is a Coleman Max which is one of the same line as the Max RWB. It has an aluminum body and is supposedly impact and water resistant according to ANSI FL1 standards. How did you have your light mounted and in what way and under what conditions did it fail?

I'll amend the original question to include: Does anyone have a recommendation for a mount that has the qualities listed above and reduces the effects of road vibration on the light?

It would also be easy to wrap a layer or two of silicone anti-vibration tape (like is sold for wrapping tool handles) around the barrel of the light before putting it in the mount.
