【Brake Warning & Automatic Illumination】This bicycle taillight features a high-sensitivity brake warning function. When it detects braking while riding, it automatically illuminates at maximum brightness for 3 seconds to alert vehicles approaching from behind. This significantly improves safety. (Works day and night, in all lighting modes.) It also has brightness detection and vibration detection functions. Brightness detection → Detects brightness and automatically turns off in daylight (bright places), and automatically turns on when approaching a dark place. Vibration detection → If the vehicle remains stationary for 30 seconds, the light automatically turns off. When vibration is detected, it turns on again. (Double-click the power button to switch between automatic mode (default) and manual mode. Brightness detection and vibration detection functions are only available in automatic mode.)
【Five Lighting Modes & Brightness Adjustment】Equipped with five lighting modes! Short-press the center button on the taillight to switch between flashing (approx. 20 hours) → breathing flashing (approx. 17 hours) → rapid flashing (approx. 18 hours) → fast flashing (approx. 25 hours) → constant light (approx. 9 hours). It also features a brightness adjustment function; in constant light mode, press and hold the button for 4-5 seconds to select from three brightness levels: high, medium, and low. It has a memory function, so upon restart, it will start from the last recorded mode/brightness.
