LED Bike Tail Light Smart Brake Sensor

Bike with safety at night with the LED Bike Tail Light FEATURES AND BENEFITS: Smart Light Sensing - Using highly sensitive smart sensor chip, able to correctly detect vibration and braking action COB LED+Ensca lens - High visibility at night but not dazzling Comparison Of Old & New Technology - Compared with the old taillights, the new Q5 taillights use more technical quality lamp beads and lenses. Make the light soft, not hurt the eyes, more secure and stable Old Model-fog Lens vs Q5-Optical Lens - Low cost, simple process, soften light by reducing brightness vs High cost, complicated process, keep light transparent and bright without glare Brake Sensing-Integrated Accelerometer - built-in accelerometer/ high performance MCU and powers by the three-level digital filter algorithm which ensure correct detecting a brake Smart Light Sense - Built-in light sensor works with vibration induction  Shock Sensing - Automatically turn off the lights when there is no vibration
