Abstract

In a method for signaling a braking process on a trailer vehicle coupled to a towing vehicle, at least one light on the trailer is actuated with an emergency brake signal during emergency braking and with a normal signal during a different driving state. The emergency brake signal causes a different actuation of the light than does the normal signal. The light can be actuated by a control signal of the towing vehicle, and the actuation state of the light can be influenced by at least one control device on the trailer. The control device detects the control signal generated by the towing vehicle and fed to the trailer to actuate the light, and analyzes the control signal. If it detects that the control signal is an emergency brake signal, it does not carry out a dedicated actuation of the light, or it effects a different actuation of the light than in other cases.
