The automatic light control system operates when the light control SW is turned to AUTO. The automatic light control sensor detects the brightness around the vehicle. The system then automatically turns on the taillights and headlights if the brightness is below the set level and turns off the taillights and headlights when the surroundings become brighter than the set level.
