I have a Blackburn Mars 3.0 which is impressive. The light comes wih a lifetime warranty, which is useful as the switch is a bit hit and miss.
I have just ordered 2 smart 1/2 watt from Wiggle
I did a bit of research, the Cherry bomb seems to be as brigh as the smart with better pattern, but it gets through batteries a lot quicker than the Smart.
So I figured, 2 smart lights would be cheaper in the long run than regularly replacing batteries on the cherry bomb, might be wrong though.
Anyone ever weatherproofed a rear light? If so, how. Tape around the edge/join doesn't seem to work.
