Clip the lightweight, durable Nite Ize SpotLit to your four-footed friends collar, and you feet ll be able to easily see him or her in the darkest night-and so will everyone else within 1000 feet of the little guy. The battery-powered LED emits a bright ambient glow, perfect for those pre-dawn or after dark outings. Choose from two modes that are simple to activate-press once for a steady glow, twice for continuous flash-and you not only help keep your pet safe, you feet ll also be able to identify him clearly from a distance. A friend has a different color SpotLit for each of his two dogs. With one on glow and one on flash mode, he always knows whos who at the dog park. The SpotLit features a durable stainless steel carabiner clip and easily replaceable batteries.
