Frequently Ask Questions & Manuals

Does the BRAKELIGHT come with a battery?
Yes, the battery is included and already inserted.
Can the BRAKELIGHT be attached to any brakes?
The BRAKELIGHT has been exclusively designed for mechanical brakes, such as cantilever dual pivot (road bike brakes) and V-brakes.
Is a minimum brake cable length required to attach the BRAKELIGHT?
To optimally attach the BRAKELIGHT, you need a minimum brake cable length (between the adjustment screw and the brake) of 25 mm.
Is it possible to replace the BRAKELIGHT’s battery?
Thanks to the integrated coin-slot cover, you can quickly and easily replace the BRAKELIGHT’s 1025 button cell battery.
Will the BRAKELIGHT damage or impair my brake cable or braking performance?
The nickel-plated brass screw with a round head and no sharp edges means that it is not possible to damage the brake cable. However, we recommend that you regularly check that the BRAKELIGHT is firmly positioned and functioning correctly. If correctly attached, the BRAKELIGHT will in no way impair the performance of your brakes.
