Question about 2003 Ford Expedition
The Lighting control module usually is the main culprit. First check if there are any blown fuses if none open this module and resolder the headlight relay terminals.

To find the problem, do a wiggle test, if they are working, go over each part that you can access from the headlights, to the light control in the car, jiggle everything around and just start with that. something is obviously loose, just have to figure out what.

The problem is fairly common in this car. The solution is the Headlight Control Module, or Lighting Control Module. My car did the same thing, they would go off, and come right back on. Then one day they went out and stayed out for 12 minutes. I changed the HCM and they never did it again. It is a box under the dash on the drivers side, right above your right shin if you were driving.
