The Nite Dawg light-up collar cover keeps your four-legged friend visible after dark. This low profile, flexible cover fits over most 1" wide collars and features a bright red LED with both glow and flash mode to keep your dog seen and safe at night. The Nite Ize Nite Dawg LED collar cover is the answer to every night-loving dog owner's problem: losing sight of their best buddy after sundown. Durable, weather resistant and lightweight, this super low-profile (not much thicker than a bandage) flexible LED illuminated strip fits comfortably over almost any dog's collar and closes securely with two micro hook-and-loop tabs. Its bright, light-transmitting polymer core is illuminated by a super efficient red LED bulb with two mode settings - flash and steady glow, and is housed in a high-quality thermal plastic urethane exterior. Visible up to 1000 feet in the dark, and powered by a long-life, easily replaceable battery (included), the Night Dawg LED Collar Cover is available in two colors, with decorative paw prints that provide passive reflectivity for visibility even when not illuminated. Simply the best way to keep your dog's presence clear and obvious, from dusk till dawn.
