🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify the correct screw tool

• Look at the two screws on the inside edge of one tail lamp (visible with the tailgate open).
• If the screw is a cross shape, use a #2 Phillips screwdriver.
• If the screw is a star shape, use a Torx T20 screwdriver.

Step 2: Remove the tail lamp screws (one side)

• Use a #2 Phillips screwdriver or Torx T20 screwdriver (whichever fits) to remove the two screws.
• Set the screws aside somewhere safe.
• Torque: No published torque spec; reinstall snug (do not overtighten).

Step 3: Pull the tail lamp housing straight back

• Grip the housing and pull it straight rearward.
• If it’s stuck on the alignment pins, gently work around the edge using a plastic trim tool.
• Pull straight back to avoid breaking pins.

Step 4: Remove the bulb socket

• Locate the bulb socket(s) in the back of the housing.
• Twist the socket counterclockwise by hand to unlock, then pull it out.
• If needed, use a flashlight to see the socket tabs clearly.

Step 5: Replace the bulb

• Pull the old bulb straight out of the socket (wear nitrile gloves).
• Install the new bulb straight into the socket until fully seated.
• Apply a light smear of dielectric grease to the socket seal area (not on the bulb glass).

Step 6: Reinstall the socket and housing

• Insert the socket back into the housing and twist clockwise to lock.
• Line up the housing alignment pins and push the lamp straight into place.
• Reinstall the two screws using a #2 Phillips screwdriver or Torx T20 screwdriver.
• Torque: No published torque spec; tighten snug only.

Step 7: Repeat on the other side

• Repeat Steps 2–6 for the opposite tail lamp.
