Parking Lamp: Description and Operation

Voltage is applied continuously to the PARK fuse to the headlamp and the Instrument Panel (IP) lamp dimmer switch through CKT 1340.

When the headlamp and the (IP) lamp dimmer switch is in the PARK or HEAD position, voltage is applied to CKT 9 thus activating the following lamps:
- The park lamps
- The side marker lamps
- The tail lamps
- The license lamps

The park/turn lamps are the only lamps that do not activate yet receive a current from CKT 9. The park/turn lamps do not activate because the voltage drop across the front side marker lamps is much higher than that across the turn lamp filaments.
