Campers, trail runners and anyone else who likes to get out in the dark knows the hassle of carrying a torch to light the way. That's why headlights are so popular. I'm a runner and like to occasionally hit the trails or go for a run around the streets when the sun isn't shining. The Energizer Vision LED Headlight is a comfortable headlamp or headtorch that keeps the lights on when Mother Nature flicks the switch.
