Claim Text:
1. A method for signaling a braking process on a trailer vehicle coupled to a towing vehicle, at least one light disposed on the trailer vehicle being operable for emergency braking with an emergency braking signal and operable for a different driving state with a normal signal, the emergency braking signal causing different operation of the at least one light than the normal signal, and the at least one light being controllable by a control signal of the towing vehicle and by at least one control device disposed on the trailer vehicle, the at least one control device comprising at least one data processor, the method comprising using the at least one data processor to detect and analyze a control signal comprising a pulsed control signal for operating the at least one light that is generated by the towing vehicle and supplied to the trailer vehicle; identify the pulsed control signal as being an emergency braking signal; and, based on the identified pulsed control signal, avoiding generation of an anti-phase pulsed control signal for the at least one light that would cancel the pulsed control signal from the towing vehicle.
