It adapts to nighttime roads with various brightness levels, providing a safe, energy-saving, and better nighttime riding experience. 【180° Wide-Angle Illumination + High-Brightness Anti-Glare Design】 The light transmission design on the sides combines with the main lamp to provide a 180° illumination range, ensuring no blind spots in the road ahead and a wider field of vision at night, completely avoiding blind spots. By adopting a fan-shaped lighting design and light reflection treatment, it effectively prevents dizziness and avoids strong light from causing dizziness to pedestrians and vehicles coming from the opposite direction while riding. It uses high-brightness LED lamps and is equipped with high-transmittance lenses, which not only demonstrates the ultra-brightness performance of the lamp beads but also significantly improves light transmittance, enhancing nighttime visibility. No matter how dark the night is, you can clearly see the road conditions at night and avoid all obstacles. 【5 Dimming Modes + Quick Close】 By lightly pressing the switch, you can simultaneously adjust the main light and side light modes, easily switching between 5 lighting modes: Sensor Mode > High Brightness → Medium Brightness → Low Brightness → Flash (10Hz). Not only can you use the bicycle light for commuting to work or school, but also for mountain climbing, night fishing, night walking, power outages, and as a substitute for a flashlight in emergencies. In any mode, if it continues to illuminate for more than 15 seconds, you can quickly turn off the light by pressing the button once. ・Type-C Fast Charging ・IP65 Waterproof
