Designed for convenient, one-handed use, the bright white LED Squeeze Light turns on when you squeeze it, off when you let go. With its rugged, heavy-duty plastic body, looped on a durable strip of nylon cord with a Size #0 plastic S-Biner for convenient attachment, the LED Squeeze Light can be easily clipped to key rings, belt loops, zipper pulls, and lanyards, making it easy for you to shine bright light instantly, whenever you need it. This lightweight, easy to use light includes two 2016 3V lithium batteries.
