A main beam switching arrangement for a road vehicle has a lighting device switchable over main beam and dipped headlamps. A sensor device determines at least one ambient parameter, and a control unit with an activatable and deactivatable automatic function automatically switches over the lighting device as a function of the ambient parameter. An operator control unit generates switchover signals by an operator to manually bring about switching over the lighting device with priority. In each case, at least one change of state of the automatic function can be brought about by a first switchover signal for switching on continuous operation of the main beam that is not occurring at the time of signal generation. By way of a second switchover signal, continuous operation of the main beam, which is occurring at the time of signal generation, is switched off.
