A 96 Bonneville should have a relay in the headlight timer circuit. Check the relay as it is most likely stuck and needs replacing
Shut the car off...lol
check the headlight/multifunction switch

On a 1999 Ford Windstar, the headlights might come on when the car is shut off because of a mechanism that allows for a courtesy light. The headlights come on for a few seconds to allow time for the driver to enter a building.
Headlights are on a relay. It may have fused shut. The relay maybe in with the fuses. Some have a delay going off which may have failed.
they turn off automatically when you shut off the car..

Square switch to the left of the steering wheel.
With the ignition off set the park brake then turn the truck on and the light will be off
