This article applies to the Ford F-250 and F-350 Super Duty (2005-2014).

Replacing a stock headlight assembly with an aftermarket one is a popular upgrade for Super Duty owners for good reason. Aftermarket lights provide a quick and easy way to improve the looks of a truck and can improve safety as well. A brighter headlight means that you can see farther down the road and spot potential hazards before they become a big problem. Replacing a headlight assembly is a quick and easy modification that anybody can complete with minimal skills and tools.

Tools Needed

  • Phillips screwdriver

Step 1 - Open the hood and locate the headlight screws

There are four Phillips screws that hold each headlight in place: two on the top and two on the bottom. The bottom two screws are located between the edge of the headlight and the front bumper, and are mounted horizontally. The top two screws are mounted vertically. Remove all four screws.

Step 2 - Remove old headlight

Push down the plastic tab located on top of the headlight. Once this tab is depressed, carefully pull the headlight away from the grill.

Step 3 - Remove bulb assembly from headlight

Squeeze the release tabs on the bulb connections (there are two bulbs per assembly), and pull the connections from the bulbs to separate them from the headlight assembly. Turn the bulbs counterclockwise to remove them from the assembly.

Step 4 - Install new headlight assembly

Replace the bulb if needed before reassembling. Insert the bulb connections into the new assembly and turn clockwise to lock it into place. Carefully press the new assembly into place and and make sure to tighten the screws well. Test the lights to ensure proper functionality before driving on the road.
