|The EL450 is perfect for occasional night rides and regular commutes. The OptiCube lens focuses the beam to help find your way through dark streets. A lockable switch eliminates accidental switch-on/off, while letting you easily toggle between high, low and flashing modes. Adjustable bracket (swings up to 90 degrees) quickly mounts to almost any handlebar, stem or helmet, and a clip lets you attach and detach the light in seconds without tools. Whether you mount the EL450 on your bike or keep it in your pack, it will always light the way. Up to 30 hours of run time on high beam on three AAA batteries (included). Waterproof to 50 meters/165 feet.
