The 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.
