Dogs just want to have fun! The fun doesn't have to stop when the sun goes down. The durable rubber GlowStreak ball features bright motion-activated LED lights. After 10 minutes of inactivity, it will automatically shut off to conserve the long-lasting replaceable batteries. About the size of a tennis ball, GlowStreak resists water and slobber, so don't worry if your dog wants to take it for a swim. It comes with a Nite Ize SpotLit LED mini-beacon for you. Set in a lightweight stainless-steel carabiner, it attaches quickly and securely to keyrings, jackets, or anything with a hook or zipper pull. The long-lasting LED provides a bright ambient glow. Use it to find items in the dark, or attach it to your jacket or backpack to make sure you're seen by others. It has two modes: press once for steady glow, twice for continuous flash. Water-resistant, long-life replaceable batteries included. Measures 8.5" x 4.1" x 2.5" Imported.
