I probably have 20 different lights for recreation in the dark. Even though I'm no longer facing AK darkness, I'm in MT and subject to exercising in the dark during the winter work week... with the dog of course! Even though my girl's got a high-vis vest, cow bell, and audio collar, having the bright light on her back adds an additional layer of confidence when I see her glow bobbing around. I love that I can use the red or green when at a campsite too, a little easier on the eyes. I just hope it lasts longer than so many products that die after a few months or so!
