Seems more and more people are being attacked and eaten by bears...I think the agressive ones have become fairly immune to trash can lid banging, screaming, and the like I suppose...I believe even air horns are becommig passe to Yogi..
..thanks for suggestion of flashbangs. I believe backpackers/ hikers would be looking for something lighter and/or smaller, dual purpose perhaps, hence my thought of a "bear-flashlight"
--but I have no idea how bears react in the wild, at night, to a sudden glare in the eyes...if lasers worked that would be ideal since they are so light weight and packable - or pocketable - of course not so effective at all in the day I guess...
do you know a source of "miniature" flashbangs??? a pocket full of firecrackers comes close, but they take time to light -- so unless you are continually smoking a stogie (like me) with which to light the things, there could be a time constraint re: charging bear...
