🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Verify the turn signal section

• Turn the hazard lights ON for 5 seconds, then OFF (no tools).
• Watch which part of the rear lamp flashes on the side you’re replacing.
• This prevents changing the wrong bulb.

Step 2: Remove the outer tail lamp fasteners

• With the liftgate open, locate the screws along the inner edge of the outer tail lamp (near the liftgate opening).
• Remove the screws using a Phillips #2 screwdriver.
• If your lamp uses nuts instead of screws on your build, remove them using a 10mm socket and 1/4" drive ratchet.

Step 3: Pull the tail lamp straight back to release the locating pins

• Use a trim removal tool (plastic) to gently start the lamp moving (do not pry on the painted bumper edge).
• Pull the lamp straight rearward with even pressure to release the guide pins/clips.
• Wiggle gently—don’t twist the lamp.

Step 4: Disconnect the wiring

• Support the lamp with one hand.
• Press the connector lock tab and unplug it by hand (no tools).
• Set the lamp on a soft towel (no tools).

Step 5: Identify the turn signal socket (bulb-type vs LED-type)

• Look on the back of the lamp for a round socket that can be removed by twisting.
• If you see a twist-out socket, it’s a replaceable bulb setup.
• If you do NOT see a twist-out socket and the back looks sealed with electronics, the turn signal is LED and the entire outer rear tail lamp assembly must be replaced.

Step 6A: If equipped with a bulb — remove the socket and replace the bulb

• Twist the turn signal socket counterclockwise by hand to remove it (no tools).
• Pull the old bulb straight out (wear nitrile gloves).
• Push the new rear turn signal bulb (amber, typically 7440/7440A) straight into the socket until fully seated.
• Reinstall the socket and twist clockwise until it locks (no tools).

Step 6B: If LED/non-serviceable — replace the lamp assembly

• Move any missing clips/grommets from the old lamp to the new lamp using a trim removal tool (plastic).
• Plug the connector into the new lamp until it clicks (no tools).

Step 7: Reinstall the tail lamp

• Align the guide pins and press the lamp straight forward until fully seated (no tools).
• Reinstall the screws using a Phillips #2 screwdriver.
• If your build uses nuts, install them using a 10mm socket and 1/4" drive ratchet and Torque to 9 N·m (80 in-lbs).

Step 8: Repeat on the other side (recommended)

• Replace the other side bulb too for matching color/brightness (use the same tools).

✅ After Repair

• Test left turn, right turn, and hazards. Confirm normal flash speed.
