The small but powerful NiteRider Stinger LED Bike Light Taillight operates off a ½ watt LED, allowing you to be seen from a half mile or more away. Whether you’re out for a quick spin around the block or a cruise down the boardwalk the Stinger will help you be seen. The Stinger Taillight was designed with the same quality and attention to detail as our high end bike lights. Battery installation, mounting and operation can practically be done with your eyes closed. Due to the ease of installation and their small size, they are quickly removed and stowed into your pocket.
