Set of 6 Lighted safety bands

Set of 6 Light-up safety bands for nighttime jogging, walking, hiking, camping or just being outside. 3 settings: static light, fast blink, slower blink. They snap closed around your wrists, ankles, neck, or dog's collar. 3rd pic shows one band wrapped around both of my ankles to show grip. These aren't coming off even with jarring movement!
