Here"s a great yet economical bike headlight, with a sleek design and white casing. It also offers CRITICAL side view, with the lens extending a bit to each side, allowing the light through. It has 3 modes - Steady, Flash, and Strobe. The steady mode is best to illuminate the path in front of you as you ride. If the road is already fairly lit, you may opt for the flashing modes. They grab the attention of motorists while conserving battery power. Takes 3 AAA batteries, included. Uses an O ring rubber mount, included. An extra one is also included.
