best battery powered bike light image

I'm working on an art project project and need a small light just to add a back glow to a picture. Just need something that is battery powered, can provide a glow and will last a long time. Longest I've found was a bike tail light that lasted 150 hours before the battery ran out.

Answer
Check it out, I am not a fan of autozone but they have some led lights they sell for 29 bucks. They are rechargable, yellow handle, about ten inches long. Light like that off the snap on truck is 139 dollars but from the zone, reasonable. Thats about the only thing I'd buy from auto zone besides an air freshener or some blinker fluid.

Hi Gideon,

I don't know of anything longer then the 150 hour one you found but what you can do is wire up a parallel battery pack.

By putting them in parallel the voltage remains the same but the capacity increases. Ten batteries in parallel would run 1500 hours or about 62 days.
