I have a Princeton Tec Quad headlamp for night hiking and other hands-free tasks, a Princeton Tec Attitude LED light for general use, and a Maglite Solitaire on my keychain. I like the Princeton Tec brand because their lights are waterproof; actually, I used the Attitude once at the summer camp where I was working to try and find a pair of glasses a kid lost at the bottom of the lake (was not successful; a scuba diver ended up being called in and did find them).
