i need a light for my helmet so i can commute back and forth to work... getting to work isn't the problem. it's the ride home at 11pm and pitch black. anybody have a suggestion for something affordable? i'm not real worried about battery life as it's only a ten minutes scoot but do need something that's fairly bright and CHEAP. I don't want to spend a hundred and some bucks for something i'm only going to use once in a while. i mean yeah i've seen the cyclops and all those lights and they look great but hell i've seen led flashlights that run off of simple c batteries that put out a good deal of light.
