Lamp, roof lighting, front (50F), CV

Front roof light bulb (50F)
Is used for general roof lighting.
The roof light is switched on either manually or automatically (the doors control the switching on/off). A lamp and a switch are built into the roof lighting unit. The switch (53) is a toggle switch with just one position. The inner lighting is alternately switched on/off with each subsequent press of the button.
The lamps are grounded with PWM from BCM. Power is supplied to the lamps from a relay controlled by the BCM. The BCM senses the supply to determine whether the relay is activated.
