Another significant advantage of rechargeable bicycle lights is their brightness and visibility. Modern LED technology has significantly improved the brightness and range of these lights, ensuring that drivers, pedestrians, and other cyclists can clearly see the person riding the bike. The increase in visibility not only improves road safety, but also enhances the confidence of cyclists in riding under low light conditions.

The main function of the headlights is to provide sufficient lighting for cyclists, so that they can clearly see obstacles, potholes, and other road conditions ahead, avoiding accidents. The main function of rear lights, side lights, and turn signals is to remind vehicles behind to avoid and reduce the risk of collisions for cyclists at night or in dimly lit environments. Modern bicycle lights mostly use energy-saving light sources such as LEDs, which have the characteristics of low power consumption, high brightness, and long service life. They are both environmentally friendly and economically practical.
