Illumination has come full circle, literally. This brilliantly durable NiteHowl LED Safety Necklace is made with flexible polymer illuminated by two bright LEDs (red, green, or blue), 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, 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. Necklace is available in a variety of colors with a battery run time of up to 60 hours. 2x replaceable 1154 batteries (red LED) or 3x replaceable 1154 batteries (blue or green LED) are included.
