Smart Brake Sensing Bike Tail Light for Night Riding

About this item

• Light-Responsive Start-Stop: Intelligently sensing surrounding light, it automatically activates in dim conditions and goes into sleep mode in bright environments (while maintaining brake light operation). When transitioning through tunnels or caves, there's no need to divert your attention to control the smart bike tail light. Featuring an IPX6 water-resistant rating, this bike brake light is suitable for use in various weather conditions.
• Automatic On/Off: In intelligent mode, the system goes into a 2-minute sleep mode when idle. Lights automatically turn on upon sensing vibration, eliminating the need for frequent manual light switching. Comes with a 400mAH battery and a USB Type-C charging cable included. Remaining battery capacity can be observed by monitoring the side ring light.
• Synchronous Mode: Stay synchronized with your team for better group travel. Double-tap to see the blue indicator light flashing, indicating the bicycle tail light has switched to synchronous mode. In synchronous mode, when two or more bike rear lights are in close proximity, all tail lights automatically synchronize their mode and blink at the same frequency. There are two installation options: saddle rail and seat post.
• Buttonless Design:Operating Instructions: To use for the first time, open the USB cover and toggle the power switch. Afterwards, use the touch-sensitive area at the center of the lampshade for power on/off. Mode Switching: 1. Long press the touch-sensitive switch at the center of the lampshade: Power on/off. 2. Single tap: Switch between 6 lighting modes. 3. Double tap: Switch between 3 modes - intelligent/manual/synchronous modes.
• Smart Motion Sensor & High LED：The built-in high-precision accelerometer, coupled with deep algorithms, swiftly detects various degrees of braking. When decelerating, the bike led light automatically illuminate brightly and remain lit for 2 seconds, conveying deceleration information to the rear. The ripple-shaped lampshade can refract light multiple times and offers six selectable lighting modes.
