We've used these when out walking at night, but we found a critical use you probably didn't think of: night lights. After my mom got her hip replaced, she needed to find her walker at night to use the bathroom. Looping one of the necklaces around the center bar of the walker solved the problem much better than her fumbling for a bed light, and we recommended it to all her physical therapists, who were impressed. We now have them sitting right below our bedside lamps. They're perfect night lights for that last minute fumbling before you go to sleep, and they don't draw any power. Perfect!
