Our Nite Ize SpotLit L.E.D. is the perfect mini-beacon whenever you need a little help in the dark. Set in a lightweight stainless steel carabiner, it attaches quickly and securely to key rings, jacketsjust about anything with a hook or zipper. Its long-lasting L.E.D. bulb provides an ambient glow bright enough for everything from reading fine print to finding your car door keyhole. Attached to things like tent lines and camping gear, it provides instant location of hazards and necessities; attached to your person (jacket, backpack, running belt) it tells other people where you are, when they might not otherwise see you. Choose from two modes: press once for steady glow, twice for continuous flash. Water-resistant, long-life, replaceable battery included.
