A vehicle's input switches relating to ignition, lights and moisture or rain provide responsive inputs that feed through a digital logic circuit to outputs of an electronic switching device for automatically activating the vehicle's lights and wipers.

An alarm may be activated if certain input switches are turned on when the ignition is off.

The digital logic circuit may be discrete, a programmable read only memory (PROM) or a programmable logic array (PLA).

The electronic switching device may constitute a driver circuit and an integrated circuit which includes both a relay switching circuit and a switched circuit, for example a metal-oxide-semiconductor (MOS) driver and a power metal-oxide-semiconductor field-effect-transistor (MOSFET) integrated circuit.
