Nite Ize Nitehowl LED Safety Dog Collar - Illumination has come full circle, literally. Nite Ize's 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 night time fun and 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 deg, making your dog clearly visible from all angles. The LEDs can be set to either flash or glow modes - great for differentiating more than one NiteHowl-wearing dog. But, as fun as it is (like a neon necklace for dogs!), 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.
