Found a cool mirror while surfing today. Looks like it could do double douty as a fire starter and signaling device. I would stick with fire though because since I havent played with it I have no idea on aiming it (also if you hit a pilot with it, could it possibly be TOO BRIGHT?). Only problem I found with it would be size. At 4.5 inches in diameter it's already leaving the EDC range. For a pack or BOB though it would be handy. You can Froogle "parabolic mirror solar light" or just go to This Random Site for an example if you don't want to do the search.
