Ford Expedition Tail Light
Torx T-15 Screwdriver
This automotive how-to guide was specifically written to assist owners of the 2003 to 2006 Ford Expedition SUV in replacing a burnt out brake / turn signal or reverse / back up light bulb in the tail light assembly.

Owners of other similar Ford vehicle models such as the Explorer, Lincoln Navigator, F-150, Lightning, Excursion, Escape, Bronco, and Sport Trac may also find these instructions to be useful.

Replacement light bulbs from Sylvania and other manufacturers have the following part numbers: Brake / Turn Signal # 3157, and the Reverse / Back Up # 3156.

The only tool needed to complete this procedure is a star bit Torx T-15 screwdriver.


Removing Torx T-15 Screw
2nd Torx T-15 Screw
To access the two Torx T-15 screws that hold the Ford Expedition tail light assembly in place, raise the rear lift gate.

Unscrew the two screws and then gently pull the tail light assembly away from the corner of the vehicle.

Pull Off Tail Light Assembly
Stop/Signal & Reverse Bulbs
At the rear of the tail light assembly, you'll see two light bulb sockets.

The one at the top of the assembly is the # 3157 combination brake, parking and turn signal bulb.

The lower bulb is the # 3156 reverse or "back up" light.


Reverse / Back Up Bulb
Brake / Turn Signal Bulb
To remove either socket and bulb from the tail light assembly, turn it 1/4 turn counter clockwise and pull it straight out.

To separate the light bulb from the socket, just pull it straight out.

If it won't come out easily, try wiggling it while pulling.

Push in a new # 3157 bulb in the upper stop/signal socket and a new # 3156 bulb in the lower reverse/back-up socket.

Test the new bulbs by having someone step on the brakes, activate the turn signal and put the SUV in reverse.

Re-Insert Tail Light Assembly
Re-insert the bulb sockets in to the housing and rotate them 1/4 turn clockwise to secure them in place.

Line up the two pegs or "spikes" on the back of the housing near the outer edge with their corresponding grommets on the rear corner of the SUV.

Push the tail light housing back in to place.

Tighten the two Torx T-15 screws in the clockwise direction until they are snug.

Try to avoid over tightening the screws to prevent from cracking the plastic inner edge of the tail light assembly.
