Query: light batteries.

The light is decent for the price.This Smith & Wesson Galaxy 3 LED Flashlight is very handy.Its not bright and the flashlight battery life doesn't seem to be good.I was thinking of keeping five on my bike for an emergency since I often forget to check my bike light batteries.UPDATE: Flashlight is garbage. Flashlight exploded after 1 month of use. Junk!
