This high-powered bike light features three high output LEDs for up to 1600 lumens of output. It has seven modes and our Tri-Focus Optics optimizes light output— this creates an ideal beam pattern for high speed. Machined aluminum construction features cooling fins and cutouts for side visibility. The Super Drive 1600XXL is both Smart Connect and Remote Switch compatible for additional ease of use. An Auto Day/Night Sensor automatically adjusts lumen output while in select modes. The light is micro-USB rechargeable and it can run for up to a massive 148 hours on a full charge. A versatile strap secures it to all common handlebar sizes.
