🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the tail lamp screws

• Put on safety glasses and nitrile gloves.
• With the tailgate open, use a Torx T25 screwdriver to remove the two tail lamp retaining screws on that side.
• Set the screws aside where they won’t get lost.

Step 2: Pull the tail lamp assembly straight back

• Grab the tail lamp and pull it straight rearward (away from the truck) to release the locating pins.
• If it’s stuck, use a plastic trim removal tool to gently help separate it. A trim tool is a plastic pry tool that helps avoid paint damage.
• Pull straight back—don’t twist the lamp.

Step 3: Remove the turn signal bulb socket

• Find the turn signal bulb socket on the back of the tail lamp.
• Rotate the socket counterclockwise by hand to unlock it, then pull it out.
• If the socket is tight, use a small flathead screwdriver carefully to help start the rotation (don’t crack the housing).

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new bulb by pushing it straight into the socket until fully seated.
• Keep the bulb glass clean (use nitrile gloves).

Step 5: Reinstall the socket and tail lamp

• Reinsert the socket into the tail lamp and twist clockwise until it locks.
• Align the tail lamp locating pins with the holes in the bedside, then press the lamp straight in until it sits flush.
• Install the two screws using the Torx T25 screwdriver and Torque to 2.5 Nm (22 in-lbs).

Step 6: Repeat on the other side (recommended)

• If you’re replacing bulbs in pairs, repeat Steps 1–5 on the other tail lamp.

✅ After Repair

• Turn the ignition ON and test the left and right turn signals.
• Verify the turn signal flashes at a normal speed (a very fast flash usually means a bulb isn’t working or isn’t seated).
• Confirm the tail lamp sits flush and doesn’t wiggle.
