This intelligent alarm works multi-functionally with sound and light taillight plus a wireless bless. Works great with a water-resistant remote control (can be used in the rainy days, snow days) in a distance up to 50m in clearings.

The alarm decibel is up to 120. As long as anybody has a touch vibration on the bike, the alarm will make a harsh sound to frighten and deter thieves. You can also warn passers when riding.
You can control all functions by pressing the 4 function buttons on the bell. So you can find your bike in darkness easily by functioning light on or sound on.

RECHARGEABLE: The Taillight comes with USB port and USB cable is included so you don't need to buy extra batteries.
