Nite Ize is known for making high quality lighting products that keep you and your pets visible and safe after dark. This rechargeable NiteHowl changes colors using an eye-catching color-blending pattern and offers three selectable colors. The cut-to-fit design makes it perfect for both big and small dogs, while the full ring of illumination helps keep your dog seen and safe at night. Our brilliantly durable rechargeable NiteHowl LED Safety Necklace is made with flexible polymer that's illuminated by bright LED's and can be recharged for hours of nighttime fun and safety. With Disc-O Select, this NiteHowl makes identifying multiple dogs easy with the ability to choose from one of three selectable colors (red, green, blue), plus a unique Disc-O mode that you'll have to see to believe. By illuminating the polymer with multiple colors at the same time, Disc-O mode creates a flowing color-blending pattern that's as fun as it is functional. To use the NiteHowl, simply trim the flexible polymer 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. Nite Ize has been creating innovative, solution-based products with quality, performance and value at the core for over 25 years. Based in Boulder, Colorado, we aim to continue offering imaginative and innovative products that make our customers' lives easier, safer and more fun.
