When you ride with Knog's Blinder Road Rear taillight, you'll be easily seen by pedestrians, motorists, and other cyclists, even on the darkest night. Few rear lights have the attention-catching brilliance of this powerful beacon. Four super-bright LEDs provide 70 Lumens, arranged to fit perfectly on your seatpost. The quick, easy-to-use silicone strap ensures this waterproof light stays securely in place. Plus, a USB plug allows for convenient recharging, and tactile buttons make for easy operation, even while wearing gloves.
