<p>A control system for turning on headlights (HL37) (and parking lights (PL39)) of an automobile when windshield wipers (wiper) are turned on, has a gating circuit (20, 21, 22) that operates relay circuits (29) to the headlights (HL37), the gating circuit (20, 21, 22) electronically latching 'in' the headlight relay circuit (29) so that the headlights (HL37) remain on when the windshield wiper (wiper) is turned off in order to avoid inadvertent turning off of the headlights (HL37) at night time and the gating circuit (20, 21, 22) electronically turning off the headlight (HL37) (and parking light (PL39)) relay circuits (29) whenever the headlight switch (12) is turned on or whenever an ignition (10) is turned off, thus assuring that the headlights (HL37) will remain on until the headlights (HL37) and ignition switches (10) are turned off. Ambient light (165) and moisture (175) sensors may be used to effect the turning on of the windshield wiper switch (11).</p> |
