System Outline
The automatic light control system works when the light control SW is turned to AUTO. The automatic light control sensor
detects the brightness around the vehicle. By this function, the system automatically turns the taillight and headlight on if the
brightness is below the regular level and turns the taillight and headlight off when the surroundings become brighter than the
regular level.
