🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the tail lamp mounting nuts

• Open the liftgate.
• Use a flashlight to find the small access cover/panel behind the rear tail lamp area inside the cargo trim.
• Use a plastic trim removal tool to carefully pop the access cover open (a trim tool is a plastic pry tool that helps prevent scratches).

Step 2: Remove the rear tail lamp assembly

• Use a 10mm socket, 1/4" ratchet, and 3" extension to remove the two tail lamp nuts.
• Support the lamp with one hand as the last nut comes off.
• From outside the vehicle, grasp the lamp and pull it straight rearward to release the locating pins/clips.
• If it feels stuck, wiggle gently—don’t pry on the paint.

Step 3: Remove the turn signal bulb socket

• Locate the turn signal bulb socket on the back of the lamp (it’s a twist-lock socket).
• Turn the socket counterclockwise by hand to unlock it, then pull it out.

Step 4: Replace the bulb

• Put on nitrile gloves to keep oils off the bulb.
• Pull the old bulb straight out of the socket.
• Push the new rear turn signal bulb (amber, 7440/7440A) straight into the socket until fully seated.

Step 5: Reinstall the socket and lamp

• Insert the socket into the lamp and twist clockwise until it locks.
• Align the lamp’s locating pins with the body holes, then push the lamp straight in until it seats flush.
• Reinstall the two nuts using a 10mm socket and 1/4" ratchet.
• Use a torque wrench: Torque to 5 Nm (44 in-lbs).
• Snap the access cover back into place.

Step 6: Repeat on the other side

• Repeat Steps 1–5 for the other rear turn signal. Replacing both keeps brightness even.
