The Nite Ize ClipLit LED is a bright, water-resistant white light encased in a durable plastic housing and molded to a rugged plastic carabiner clip.
A quarter turn clockwise switches the light on. This is super easy to use, switching off simply requires a quarter turn anti-clockwise. The clip has the same profile as the clips on the S biner and has the same gate system. The clip seams pretty robust. I haven’t managed to break one yet.
