I'm looking for something I can put on my helmet so cars see me. I know of the planet Bike and other very small flashers, but they run on lithium coin cells, and I'd rather have something that uses standard AAA eneloops. I was hoping DealExtreme would have a <$10 little flashlight with a flash mode, but I only see AA ones, which would be getting a little large. I have a L2T-v2 for throwing light, but want something small and blinkey to make sure I'm seen while commuting every day. Any suggestions? I know that some of the $40+ lights have a strobe mode, but that is too much more expensive than the coin cell lights...
