The Secuzed E Brex from Busch+Müller is compact and light weight.  It incorporates the light and reflector in one unit.  It can be fitted to the seat post or the mudguard as required.  The Brex technology incorporates an integral sensitive acceleration sensor. This detects every braking process and differentiates the different braking intensities. The rear light is controlled accordingly: normal operation; braking or emergency braking. The integrated sensor means that a wiring connection to the brake is not required, unlike with previous brake tail lights

In the centre of the rear light is the Z reflector, which is as small as possible thanks to the new prism technology from Busch+Müller. This compact reflector fulfils all the required of the German Road Traffic Licensing Regulations (StVZO). This minimalist reflector is surrounded by a ring of ten super bright LEDs. The highest possible safety is offered thanks to the special arrangement of the LEDs the rear light; thus making it easy to see even in difficult visibility conditions. Two tail lights symmetrical to the longitudinal axis of the vehicle are required for strut mounting.

The Secuzed E Brex has two lighting modes to choose from:

1. Permanent mode:  The rear light is permanently illuminated in the driving light mode when the lighting system is switched on. Brake and emergency brake light functions are switched via the sensor control.
2. Senso mode: When the ambient brightness is sufficient, the driving light is automatically switched off.  When it is dark or with diminishing ambient brightness the driving light is automatically switched on. For example while riding through a tunnel or at twilight.  The sensor control switch on the the brake and emergency brake light functions as required

What is Brex?

Rear brake light functionality including an emergency hard brake signal. The integrated Brex sensors recognise any braking process and have the capacity to differentiate between standard braking and emergency braking.  With normal or standard braking the central Brex light portion will illuminate to signal the manoeuvre to following traffic.  In an emergency braking situation the Brex area will flash a visual alarm to the rear warning other road users and helping to avoid severe accidents

For use with E-Bikes only

​Please note the following recommendations from Busch+Müller if you are planning to install your own E-Bike lighting system: 

• Establish and/or measure the voltage on the cables or connecting point intended for the connection. Make sure this is within the parameters of the light specification
• Establish and/or measure the polarity of the above mentioned connection and make sure to connect respectively to the correct pole using the instructions and/or the + / - signs on the light
• If you are not able to establish either of the above, or are not sure then please refer to your local electric bike specialist to install the lights for you
