The built-in brake sensor automatically switches to the highest output when braking, to warn people behind you that you've slowed down a lot. An integrated ambient light sensor adjusts the brightness based on the surroundings automatically. When you aren't riding, the taillight will enter into sleep mode after 5 minutes of inaction and auto-activate on any vibrations. In this way, there are no worries when you stop riding and waiting for the green traffic light. Just take a break, and forget about it. Under 10% power, the tail light will automatically turn on the low battery mode (group ride) and turn off the sensors to achieve longer battery life.
