ABSTRACT:
An automatic headlight extinguishing switch apparatus especially adapted to interfit with an existing automobile light switch member which comprises a switch means and a wiring harness. The headlight extinguishing switch apparatus comprises an adapter apparatus which interfits between the switch means and the wiring harness, and a normally open pressure sensitive switch device which is operatively connected to the adapter apparatus. The pressure sensitive switch device is adapted to be connected to an automobile vacuum line or an automobile pressurized oil line, such that the switch will be closed when the engine is turned on and will open when the engine is turned off. A manually operable override switch member is provided which bypasses the pressure sensitive switch device and permits the automobile lights to be operated when the engine is turned off.
