🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the tail lamp fasteners

• Open the liftgate.
• Locate the two tail lamp retaining nuts on the inside edge of the tail lamp (accessible with the liftgate open).

Step 2: Remove the tail lamp retaining nuts

• Use a 10mm socket, 1/4" drive ratchet, and extension to remove the two nuts.
• Set the nuts somewhere safe so they don’t get lost.

Step 3: Remove the tail lamp assembly

• Grip the tail lamp with both hands and pull it straight rearward to release the alignment pins.
• If it feels stuck, use a trim removal tool to gently help it pop free at the edges.
• Pull straight back, not sideways.

Step 4: Remove the rear turn signal bulb socket

• Find the turn-signal socket on the back of the tail lamp (the socket that lines up with the amber turn section).
• Twist the socket counterclockwise by hand and pull it out.

Step 5: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new bulb by pushing it straight in until fully seated.
• If your bulb has a number printed on it, match that number when buying replacements.

Step 6: Quick test before reassembly

• Reinsert the socket into the tail lamp and twist clockwise to lock.
• Turn the ignition ON and activate that turn signal to confirm it flashes normally.
• Turn ignition back OFF when confirmed.

Step 7: Reinstall the tail lamp assembly

• Align the tail lamp’s guide pins with the body grommets and press the lamp straight forward until it seats flush.
• Install the retaining nuts by hand first to avoid cross-threading.
• Use a 10mm socket and torque wrench (in-lb) to tighten the nuts: Torque to 5 N·m (44 in-lbs).

Step 8: Repeat on the other side

• Do the same steps for the other rear turn signal.
• Replace both sides for even brightness.
