Cleverly engineered to warn other road users when you're slowing down, this rear light is equipped with an accelerometer. This special technology boosts its brightness to 100 lumens as your speed decreases. This makes it a perfect brake light for alerting traffic behind you in the exact same way as a car's brake light does. Coming complete with a silicone strap, this handy rear light easily mounts to your seatpost without the need for any tools.

Brake with confidence
Let traffic know you're slowing down with the Lumasense's clever accelerometer that increases brightness as your speed reduces.
