If I had all my flashlights spread before me and I could only take one; it would be my Petzl Zipka Plus with its pouch. The Zipka is a headlamp with an extractable cord instead of a headband. It works well as a headlamp, handheld light, tent light, trail light and emergency strobe light. I would carry it, in the pouch, on my belt. It is currently attached to the shoulder strap of my CamelBack. It is not super bright but it shines for a long time on 3 AAA batteries. I first saw one on the Survival and Outdoor Safety web site by Gene Ward. The more I looked at it and thought about it the more it looked like a good PSK survival light.

But, I carry red and ultra-violet Photon I Coverts on my keychain. A CMG Infinity Ultra AA LED in my pocket and a SureFire C2 on my belt. I also have a SureFire G2 sitting in a car door pocket in my car. Plus I have one of the cheap 6 volt lantern battery flashlights in the back of my SUV. Also a white Photon III Covert in my first-aid kit in my PSK.
