Here's a handy way to create flexible, two-sided illumination almost anywhere, over and over and over again. An ecologically responsible alternative to disposable chemical glow sticks, the Nite Ize LED Clip-On Marker is a flexible polymer strip encased in lightweight, durable nylon fabric. Decorated with a reflective pattern for extra visibility, the Clip-On Marker is illuminated on both sides by an efficient (over 100,000 hour) LED and powered by a 2032 replaceable battery (included). Lightweight, thin, and weather-resistant, its sturdy plastic S-Biner Clip can be attached to almost anything with a hook or ring - from zippers and tent lines to belt loops and bicycle seats. It has a S-Biner double gated carabiner clip on the opposite end, too, so you can also clip it to itself and create a loop of light to wear on your wrist, or wrap around anything up to 3" in diameter. The bright red LED has two modes to choose from - steady glow or continuous flash. Perfect for creating safety visibility in any situation - every glove box should have one!
