- Smart Bike Tail Light with Alarm : This is more than just a bike rear light; it features a built-in anti-theft alarm. With a movement sensor and vibration alarm, this tail light can deter thieves with a loud 110dB alarm, providing extra security and peace of mind while your bike is parked outdoors. - Adjustable Sensitivity : The vibration sensitivity is adjustable across seven levels to suit your needs. Easily change settings to avoid false alarms from light touches or minor movements. - Automatic Brake Light : Equipped with an automatic bicycle brake light that activates via a sensor, it alerts drivers behind you when you brake, effectively preventing rear-end collisions and enhancing safety. Choose from four light modes: slow flashing, breathing, rapid flashing, or steady light, easily controlled via a wireless remote. - Intelligent Auto On/Off Function : The tail light features built-in light and motion sensors. In dark environments, it will automatically turn on and off after 30 seconds of inactivity. In bright conditions, it conserves battery by turning off automatically. For daytime use, select the rapid flashing or steady light modes, which do not have the auto feature. - Easy Installation : Includes two mounting methods for versatile installation options. The provided bracket is ideal for tube mounting, while zip ties work well for irregular surfaces. Quick and hassle-free installation makes this an affordable, practical accessory for any bike.
