Welcome to a whole new world of nighttime visibility. Two ultra-bright LEDs send light through an integrated optical fiber to create full-length illumination so bright you need to see it to believe it. Featuring the convenience of rechargeability and easy push-button operation, this leash glows for more than six hours on a single charge. Nite Ize optical fiber technology transmits light throughout the entire length of this eye-catching leash without loss of light output and offers both constant glow and flash modes. Featuring a comfortable, padded handle with a built-in anchor point, this highly water-resistant leash is made to last.
