The Nite Ize ClipLit LED is a bright, water-resistant white light encased in durable, plastic housing and molded to a rugged plastic carabiner clip. Easy to activate—a quick twist turns it on and off—it's just as easy to clip onto and off of almost anything with a loop. Attach it to your key ring, belt loop, zipper pull, backpack or purse, and you'll have efficient, bright illumination wherever you are, whenever you want. The ClipLit is perfect for everything from reading fine print to finding a keyhole. And, when it's attached to your clothing, it's a fun and stylish way to let people know where YOU are when it's dark, increasing your visibility and safety.
