WEST BIKING SM2 Smart Brake Sensing Bike Tail Light | 180° Wide Angle LED | Digital Battery Display

The WEST BIKING Smart Sensor Bike Tail Light is a revolutionary safety upgrade designed for modern cyclists, ensuring maximum visibility and peace of mind on every ride. Utilizing a high-brightness COB LED core and a massive 180-degree wide-angle design, this smart light cuts through the darkness and constantly reminds surrounding vehicles and cyclists of your presence.

At the core of its intelligent operation is a dual-chip system featuring a highly sensitive Motion Sensor and an Ambient Light Sensor. This allows the light to automatically adjust output for energy saving and instantly wake from auto-sleep upon sensing vibration when you start moving. The light boasts a powerful Brake Sensing function that instantly triggers a saturated, full-coverage red light when deceleration is detected.

Designed for convenience and durability, it has a real-time digital display that shows the exact battery percentage and the current mode. Rated IPX4 water resistant, it remains resilient against rain and daily weather impacts. Charging is simple and fast thanks to the universal Type-C port, and a mode memory function ensures it always restarts in your last-used setting.

The package includes two dedicated mounting brackets, offering versatile installation options for both saddle rails and seat posts. With 5 distinct light modes and a potent 400mAh battery, this WEST BIKING tail light is the essential piece of gear for safer, smarter cycling.
