Not certain but presumably there some kind of accelerometer sensor inside, similar to that in phones etc.
The light has three LEDs and two settings.
One is auto, which turns on the top LED when the light level drops in the evening.
The second setting has the top LED on all the time.
Both settings have brake light function enabled. When you slow down all three LEDs light up solid for a few seconds, if you slow down sharply all three LEDs flash for a few seconds.
I bought a set of these, good focused beam on the front light and when riding the rear light seems to do as described as in the harder you brake the brighter it gets, the front one would be better with a flash function but good otherwise.
