A control system for turning on the headlights (and parking lights) of an automobile when the windshield wipers are turned on, has a gating circuit that operates relay circuits to the headlights, the gating circuit electronically latching "in" the headlight relay circuit so that the headlights remain on when the windshield wiper is turned off in order to avoid inadvertent turning off of the hedlights at night time and the gate circuit electronically turning off the headlight (and parking light) relay circuits whenever the headlight switch is turned on or whenever the ignition is turned off, thus assuring that the headlights will remain on until the headlights and ignition switches are turned off. The relay circuits controlled by the gating circuit may operate a mechanically or electrically latched relay device to hold the headlights (and parking lights) on until the relay circuit controlled by the gating circuit operates the mechanically or electrically latched relay device to turn the headlights off. Ambient light and moisture sensors may be used to effect the turning on of the windshield wiper switch.
