When you're walking or running your dog before sunup or after sundown, you sometimes worry that other people and cars can't see you coming. Unless, of course, you're using the Nite Ize Nite Dawg LED Dog Leash. With its 18-in. flexible, LED light-transmitting polymer core and a reflective stripe for passive reflectivity, this leash makes both you and your furry friend's presence obvious to everything on-coming, from dusk till dawn. Made of high-quality, durable nylon and measuring 5 ft. in length, the Nite Dawg leash features a weather-resistant, enclosed switch that allows you to choose illumination modes (glow or flash). Its efficient LED has a life of about 100,000 hours and a replaceable 100-hour battery is included. Secured to your dog's collar with its strong, rotating spring clip, this leash provides visibility through endless late-day, late-night and early morning outings. (Doubly effective when paired with the Nite Dawg Collar.)
