A motor vehicle hazard warning system circuit has a flasher unit, at least one flasher lamp which is connected to a flasher-unit driver output, a hazard warning activation switch which engages in an actuation line, which activates a hazard warning mode of the flasher unit, and a hazard warning monitoring lamp which is actuated in each case by the flasher unit, specifically so as to flash in an active hazard flashing mode, and in an inactive flashing mode according to a dimmed vehicle search light signal, via a separate output driver. A connection line for the monitoring-lamp control device is connected on the control drive-side to the driver output for the at least one element which can be operated intermittently, and one multi-level switch with at least two permanent switched positions is provided, which multi-level switsh is looped with a first switching level into the actuation line, which activates the intermittent mode of the control device and is looped with a second switching level into the connection line for the monitoring-lamp control device. The intermittent mode is activated via the one switching level in one of the switched positions of the multi-level switch and the electrical connection between the monitoring lamp and the flasher-unit driver output is closed in synchronism therewith via the second switching level.
