Gut a moose in the dark by yourself and you'll never again be without a headlamp!
No kidding, I had 3 in my pack this fall on a bull after dark by myself. Just in case...
But I carry a scorpion for other tasks that need brighter light for less time, uses for all, but I generally always have 1 or 2 headlights in my backpack at all times.
I don't have one bright enough to do blood trails with though. So I bought a coon hunters headlight for that. Just wished I could find a 6 v halogen bulb to fit it too...
