System Outline

The automatic light control system operates when the light control SW is turned to AUTO. The light control sensor detects the ambient light around the vehicle. The system then automatically turns the taillights and headlights on if the light brightness drops below a safe level and turns them off when the ambient light becomes bright enough to drive safely.
