Büchel Duo LED Stoptech

LED rear light “Duo LED StopTech” with integrated Li-Ion battery and intelligent brake indicator function day/night, StVZO approved.

Standard in cars and motorbikes, still rather the exception in bicycle lighting: the brake light. The intelligent brake light function (“StopTech”) of the rear light “Duo LED” makes cycling safer. A deceleration sensor activates another LED when the speed is reduced, thus clearly warning following road users.

During the day, by the way, it works the same way as with the car. The tail light is not lit, only the brake indicator function is active. In the dark, at dusk or in subways, a brightness sensor then automatically activates the rear light.

This technology is a joint development with the Fraunhofer Institute. The rear light can be easily attached to any seat post with the included bracket.
