Circuit Description
For the visibility of driver, the auto light sensor controls automatically the head lamps and tail lamps through relay coil control. When the light switch in AUTO and the auto light sensor detects low intensity of illumination, ground is provided to the head lamp relays through auto light sensor Battery voltage is supplied to the head lamps through head lamp fuses and head lamp relays(high/ low) contact
Auto light sensor sends output signals to the BCM and the BCM controls the tail lamp relay Of course, the head lamps and tail lamps can be controlled independently by using light switch and dimmer/passing switch.
