VEHICLE LIGHT, WINDSHIELD WIPER CONTROL SYSTEM

摘要

A control system for automatically turning on the headlights (and parking lights) of a vehicle has an input section that includes the ignition switch (15), the manually operated windshield wiper switch (16), and condition responsive light sensor (17) and moisture sensor (18) switches. The switches operate through a logic circuitry (12 and 13) through an output section to turn on and to keep turned on the lights when any of certain switch combinations are turned on: a) ignition (15), windshield wiper (16), light sensor (17) and moisture sensor (18); b) ignition (15), windshield wiper (16) and light sensor (17); c) ignition (15), windshield wiper (16) and mois- ture sensor (18); d) ignition (15) and windshield wiper (16); e) igni- tion (15), light sensor (17) and moisture sensor (18); f) ignition (15) and light sensor (17); or g) ignition (15) and moisture sensor (18). In the event that the windshield wiper is turned off the light level sen- sor (17) causes the lights to be turned off. The windshield wipers are turned on with the following switch combinations even though the manual windshield wiper switch (16) is turned off: a) ignition (15), light sensor (17) and moisture sensor (18); or b) ignition (15) and moisture sensor (18).
