This automotive maintenance tutorial was specifically written to assist owners of the 4th generation (2018, 2019, 2020 and probably also the 2021, 2022 and 2023 model years) Ford Expedition SUV in changing a burnt out fog light bulb located in the front bumper cover.

Owners of other Ford or Lincoln vehicles such as the Explorer, F-150, Escape, EcoSport, Transit, F-350, F-250, Edge, Flex, Ranger, Fiesta, Focus, Fusion, Mustang, Bronco, Super Duty, Navigator, Continental, MKZ, MKX, MKC, MKT, Aviator, Corsair and Nautilus may also find these DIY instructions to be helpful.

The compatible replacement halogen light bulb part number is H8 which is available from various manufacturers such as Sylvania, Philips and Osram.

If you would like to have brighter fog lights that will also last a lot longer before burning out, install some H8 LED bulbs.

No tools are needed to access and replace the fog light bulbs on either the driver or passenger side of the vehicle.

Make sure that the transmission is in "Park" and engage the emergency / parking brake so that the vehicle won't move unexpectedly.

Look under the front bumper cover and locate the back side of the fog light housing and the old light bulb.


Grey Electrical Connector
Disconnect Power Plug
Base of Old Light Bulb
Gently pull back the two tabs on the sides of the electrical connector to release the retaining clips before sliding the power plug straight off the base of the old light bulb.

Avoid bending the tabs back too far to prevent from having them break.

1/4 Turn Counterclockwise
Old Light Bulb Removed
Halogen Bulb
Rotate the base of the old light bulb 1/4 turn in the counterclockwise direction before pulling it straight out of the housing.

The OEM (original equipment manufacturer) fog light bulb part number in this 2018 Expedition MAX was a Philips H8 12V 35W halogen.

1/4 Turn Clockwise
New Bulb Installed
Avoid touching the glass part of the new halogen bulb with your fingers or anything dirty in the bumper cover.

If you do get the new bulb dirty, wipe it clean with a paper towel and some rubbing alcohol.

For brighter fog lights that will also last a lot longer before burning out, install some compatible replacement H8 LED bulbs.

Insert the new bulb into the housing and rotate it 1/4 turn in the clockwise direction to secure it into place.

Push On Power Plug
Connector Secured
Test New Fog Light Bulb
Slide the electrical connector straight into the socket on the new light bulb.

You should feel or hear the power plug "click" securely into place.

Double check that the new light bulb and electrical connector are properly installed.

To test the new light bulb, turn on the headlights and then switch on the fog lights.

Be sure to write down the bulb change in your vehicle's service records.
