Equipped with six powerful lamps, it provides up to 1000 lumens and illuminates up to 300 meters (high beam). The 190° wide beam illuminates a wider area than normal, making it easier to see not only the road ahead, but also oncoming vehicles and pedestrians on both sides. It has five modes - high, medium, low, flashing and SOS - and can be adjusted to suit road conditions and the scene. It protects you from accidents on the road at night, making it useful for a variety of situations, including commuting to work or school by bicycle, road bike, cross bike, cycling, and outdoor activities. By illuminating the darkness, they improve visibility when driving at night, alerting drivers and pedestrians to the presence of cyclists, and the taillights also make your presence known to cars behind, providing peace of mind when driving on dimly lit roads at night with few streetlights.
