A while ago I acquired a coin-cell operated compact headlamp. I have grown to really like this headlamp, and have since embarked on a quest to find and try others like it. My favorite thus far is the Petzl e+lite.
The e+lite offers 3 modes (economy intensity, high intensity, flash) of white light from 3 LEDs, and two modes (steady and flash) of red light from a single, smaller LED. The e+lite operates via a rotating switch which has a an off position at each end of it's range of motion, plus a lock position. The lamp is mounted on a ball joint and can be swiveled into a mulitude of positions. It can also be turned around 180 degrees so the lamp face is against the base for added protection. The base also has a built-in clothing/hat clip. It came in a nifty little hard case, it runs on 2 CR2032 batteries, and per Petzl it has a run time of about 40 hours on econo mode.

Because the coin cell batteries have such a long shelf life (about 10 years), I think the e+lite would make a great addition to an emergency kit or other gear kit.
