🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the tail lamp screws

• Open the liftgate and locate the two screws on the inboard edge of the tail lamp (the side closest to the liftgate opening).
• Use a Phillips #2 screwdriver to remove both screws.

Step 2: Pull the tail lamp assembly free

• Grab the tail lamp with both hands and pull it straight back from the body.
• If it’s stuck, use a plastic trim removal tool to gently start the separation.
• Tip: Pull straight back to protect the alignment pins.

Step 3: Remove the turn signal bulb socket

• Find the turn/stop bulb socket on the back of the tail lamp (it’s a twist-lock socket).
• Twist the socket counterclockwise by hand and pull it out.
• Use a flashlight if needed to identify the correct socket.
• Definition: A “twist-lock socket” unlocks with a short twist instead of screws.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new 3157 bulb by pushing it straight in until fully seated.
• If you have it, apply a very light film of dielectric grease to the socket seal (not on the bulb glass).

Step 5: Reinstall the socket and test

• Insert the socket back into the tail lamp and twist clockwise until it locks.
• Turn the ignition to RUN and switch on the turn signal to confirm it flashes normally.
• If it doesn’t work, turn ignition OFF and re-check the bulb seating and socket lock.

Step 6: Reinstall the tail lamp

• Line up the tail lamp alignment pins with the body holes and press the lamp straight in until fully seated.
• Reinstall the two screws using a Phillips #2 screwdriver.
• Torque to 3 Nm (27 in-lbs)

✅ After Repair

• Verify the rear turn signal flashes at a normal speed on both sides.
