The compatible replacement light bulb part numbers are as follows: Brake / Rear Turn Signal # 7443, Reverse # 7440 and Parking Light # 194.

The tools needed to access and replace the light bulbs include a pop rivet removal tool and/or a flathead screwdriver.

There are two round plastic pop rivets and two cargo net hooks holding the carpeted trunk liner in place to the rear corner of the trunk.

Use a pop rivet pry bar tool, a flathead screwdriver or a pair of needle nose pliers to gently pull out the two pop rivets.

Remove the two cargo net hooks by turning them counterclockwise.

Gently pull back the trunk's carpet liner to reveal the two bulb sockets.

Rotate the bulb socket 1/4 turn counterclockwise before pulling it straight out of the housing.

Pull the old light bulb straight out of the socket.

Re-insert the socket in to the housing and rotate it 1/4 turn clockwise to secure it in place.

The reverse ("back up") light bulb socket is located at the bottom of the housing.

Rotate the bulb socket 1/4 turn counterclockwise before pulling it straight out.

Push a new number 7440 light bulb in to the socket.

Re-insert the bulb socket in to the housing and rotate it 1/4 turn clockwise to secure it in place.

Line up the holes in the trunk liner with their corresponding holes in the metal panel on the rear corner of the trunk.

Push the two pop rivets back in to place.

Use the pop rivet removal tool to pry out the two pop rivet friction fasteners located closest to the light housing.

I just carefully used a screwdriver to pry off the rubber bumper cover since I wasn't aware of the slots with a larger hole and a smaller hole used to secure the small rubber pegs in place.

Set the two pop rivets and the rubber trunk bumper piece aside in a safe place.

Rotate the bulb socket 1/4 turn counterclockwise and pull it straight out of the housing.

Push a new number 194 light bulb straight in to the socket.

You can also use a brighter 194 LED bulb.

Re-insert the bulb socket in to the housing and rotate it 1/4 turn clockwise to secure it in place.

Line up the three pegs on the back side of the rubber bumper with the larger holes in the trunk lid.

Push the rubber bumper in to place and slide it towards the center of the trunk and also the outer edge down to secure the rubber pegs in to the smaller openings.

To test the new tail light bulbs, have someone step on the brake pedal, activate the hazard signals and place the transmission in reverse.
