Magicshine Taillight Seeme 150

The built-in brake sensor automatically switches to maximum power when braking to warn those behind you that you have braked hard. An integrated ambient light sensor automatically adjusts the brightness to the surroundings. If you are not riding, the rear light switches to sleep mode after 5 minutes of inactivity and activates automatically every time you vibrate. This way, you don't have to worry when you stop driving and wait for the green light. Just take a break and forget about it. When power consumption is less than 10 %, the rear light automatically switches to low battery mode ("Group Ride") and switches off the sensors to extend battery life.
