<p>The circuit for a vehicle includes a set of switches attached to each of the opening doors. When a door is opened the corresponding switch is turned on connecting a warning light and audible warning device to the supply. At the same time power is supplied to the hazard flasher light circuit, so that they may operate under the control of the flasher control unit. The additional circuitry may be added to the normal hazard flasher circuit without disruption of this circuit, by means of a pair of connecting terminals. The warning may be provided by simultaneously activating all four turn indicators and the courtesy light.</p> |
