In the 1983 Lincoln Mark VI, the headlamp switch is typically located on the dashboard, to the left of the steering wheel. It is usually integrated into the instrument panel, near the climate control and other accessory switches. Look for a round or rectangular knob that you can pull or twist to activate the headlights.
