86 F150 Headlights flicker

When I hit bumps or even rock the truck the headlights flicker. They don't go off they just flicker and get dimmer. Could it be a short or a loose wire. Both headlights do it at the same time.

Thanks
Nolan

nhawki00, Check the wiring assembly plug that connects to the tabs on the bulb. The wire contacts inside the plastic plug may have loosened up and slid backwards into the plug. So even if the plastic plug is firmly connected to the bulb, the internal power tabs in the plug may not be making full contact with the bulb tabs. Firmly push on the wires toward the bulb so that the contacts in the plug hook up with the bulb tabs.
