I found a small red LED lite a couple years ago at the MSBA show and love it. It clips to the bill of my cap and is powered by what appears to be a watch battery.

I try not to use light, but when needed it works great. Does anyone know where to buy these? I can't remember the name and have not seen them anywhere. The whole thing is the size of a AA battery...

Saw some at wally world

I picked one up that is half the size of an AA battery from joe lyons at surfcasting RI. LOVE IT.

Thanks Zacs, different than mine but looks like it will work just fine...
