Probably the best battery powered tail light on the planet! * Half-watt BlazeTM LED plus 2 eXtreme LEDs for visibility up to 1 mile * Unique, eye-catching flash pattern * Flashing and steady mode * Ultra compact vertical design is weatherproof, lightweight and durable * Includes bike mounts and clip mount for multiple mounting options * Up to 100 hours of run time on 2 AAA batteries (included) There are two versions, or colors, of this light. One with a red lens and white body and another with a clear lens and black body. But they both emit a red light so the difference is simply cosmetic.
