ABSTRACT OF THE DISCLOSURE Warning Lamp sequencer circuits for school buses of the type employing both a warning light flasher and a stop arm, operably connected to the school bus door. The warning lamp flashers are activated and the stop arm pivoted to horizontal position, either by throwing a single "initiate" switch or by opening of the school bus door. The circuit employs a series of relays and associated coils, such that a single initiate switch may be employed to activate the warning light flasher and stop arm components, as the school bus door is opened. In a modified circuit, the warning light and stop arm components may be activated automatically, as the school bus door is opened.
