Illumination has come full circle, literally. Our brilliantly durable NiteHowl LED Safety Necklace is made with flexible polymer illuminated by two bright LEDs, and simply slides over your dog's neck for hours of nighttime fun & safety. Just trim the tube to a custom fit, give the button on the durable, weather resistant housing a quick press and the entire collar lights up a full 360 degrees. The LEDs can be set to either flash or glow modes-great for differentiating more than one NiteHowl-wearing dog. But the best thing about the NiteHowl is that it keeps you and your buddy seriously safe on those after-hours walks, romps in the park, and campsite moon-howling sessions. Easily slides over your dog's neck as a bright LED addition to an existing collar. Details: Battery run time: 60 hours Weather resistant 3x replaceable 1154 batteries included.
