Ford F-150/F-250: How to Replace Fog Lights

Fog lights are not only useful but they add a nice touch to your Ford F-150 or Super Duty. Here is how to install fog lights yourself.

This article applies to the Ford F-150 (2004-2014) and F-250, F-350 Super Duty (2005-2014).

You don't have to live in London or San Francisco to appreciate and even use fog lights. Mounted below your headlights, they are specially constructed to cast a low, wide, beam to help you see the road under the fog, dust, or snow. Just as they are for your headlight bulbs, fog light bulbs are available in halogen, HID (high energy discharge), and LED types. Installing new halogen bulbs is fairly straightforward and inexpensive. HID and LED lights will require ballasts and wiring harnesses that will have to be attached to your truck frame. This coupled with the high voltage required for HID bulbs, may prompt you to have a professional do it.

Step 1 - Access the fog light bulb

Depending on the model year, your F-Series fog light bulb will either be accessible by removing the fog light housing to access the bulb, or by simply reaching up behind the bumper to twist the old fog light assembly out.

  • Make sure to turn off your truck.
  • Open the hood. This allows light into the area where you will be working.
  • Reach behind the bumper and turn the fog light housing counterclockwise to remove it from the bumper housing.
  • Disengage the holding clip on the light bulb housing. This will release the bulb from the wiring. You may need a flathead screwdriver to ease the clip up.
  • Remove the bulb from the housing.

Step 2 - Install the new bulb

  • Carefully place the new fog light bulb back in the wiring socket and make sure the clips secure it again.
  • Be cautious not to touch the new bulb with your fingers.
  • Re-insert the fog lamp housing back into the bumper housing. Turn the lamp clockwise until it clicks in.
  • Close the hood and you're done.

Pro Tip

It's important not to touch the new bulb with your fingers as oil from them will overheat the bulb where you touched it and cause the bulb to burn out faster.

Again, HID and LED fog lights require the installation of ballasts and wiring harnesses. Unless you have some experience with this, and the right tools, you may want to consider having a professional do it.
