Abstract
The automated switching of a vehicle lighting system is to be made more reliable. To this end, it is provided that the entire data flow from the sensors to a lighting device, which receives the control signals from a transmission module, is implemented in dual-track fashion throughout. This provides the corresponding redundancy and increases the required reliability. It is provided, in particular, to transmit to the lighting device a control signal and a correspondingly negated signal, so that the lighting device is able to check whether the data processing and data transmission are free of faults.
