Two weeks ago, I was out for a night ride on some local mountain bike trails with a buddy. The trails were in great shape, and we were climbing a big hill about halfway through our ride when my cycling headlamp's rechargeable battery failed. We were about five miles from the car, and the only way out was by single track far too narrow for a vehicle. Lucky for me, I had my SureFire E1B Backup® in my pack. I strapped it to my helmet and had more than enough light to finish the ride in style as something an average flashlight wouldn't have been able to muster. My E1B is always close at hand when I venture into the woods, and that night it lived up to its name.Thanks, SureFire.
