Parking Lamp: Description and Operation

CIRCUIT OPERATION
The headlamp switch has three positions: OFF, PARK (parking lamps) and ON, plus a dimmer switch. When the headlamp switch is in the PARK or ON position, the switch connects circuit F33 to circuit L7. From the headlamp switch, circuit L7 branches to power the front parking lamps and rear tail lamps, roof identification lamps, fender lamps and rear license plate lamps. Circuit Z1 provides a ground for the parking lamps. Ground for the roof clearance and identification lamps is supplied on circuit Z4.
