[Charging Required Before First Use!!!] When using the taillight for the first time, be sure to fully charge and activate the taillight using the included Type-C cable before use.
[Bicycle Taillight & Anti-Theft Alarm] The Onvian bicycle taillight is equipped with 31 high-brightness LED lights, making it a bright and essential accessory for bicycles, both day and night. It features 5-in-1 functions: warning light, brake warning light (built-in G-sensor), turn signal light, bicycle bell, and anti-theft alarm, meeting various riding needs in daily life. While riding, you can use the left and right turn signal lights to alert surrounding vehicles and pedestrians and avoid them. After parking, remove the remote control to lock the smart taillight alarm host, putting your bicycle in anti-theft mode and preventing theft at night.
[6 Light Modes] The bicycle taillight's light modes switch in the following order: slow flash → breathing → burst flash → constant light → emergency flash → OFF. The taillights only have slow flash and breathing modes; AUTO mode is enabled (see the details page for an explanation of AUTO mode).
[Brake Warning Light Function] The brake light turns on when the taillights are in one of four lighting modes: slow flash, breathing, constant illumination, or emergency flashing. This means that when deceleration is detected, the brake light automatically flashes brightly for 2 seconds, warning following vehicles and effectively preventing rear-end collisions, thus reducing traffic accidents.
[Turn Signal Light Function] When riding, pressing the left or right turn button on the road bike light will signal your direction of travel to following vehicles when visibility is poor. The taillights will beep during left or right turns, continuing for 2 minutes before automatically turning off. To end the beeping earlier, press the left or right turn button again.
