I have a great flashlight on my christmas list. It is white LED, has transparent plastic case,
floats, has NO battery at all! It has a coil of wire (you can see it in there) and a metal slug that
slides back and forth through the coil when you shake it. That motion generates a current that
charges a small capacitor. The capacitor powers the LED for up to 5 minutes (advertised). I saw one,
and used it, in Hawaii this last summer. Solid item, well-built. Gotta have
it.

Don't see why this wouldn't work with an LED flasher, except maybe the flasher would run longer. I
'spose a person could patch in a capacitor for the flasher.
