🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the taillight service opening

• Use a flashlight to find the access cover in the trunk side liner behind the taillight.
• If there’s a small cover, pry it open gently with a plastic trim removal tool.
• If there are push-pins/clips, lift the center carefully with a small flathead screwdriver, then pull the clip out with the plastic trim removal tool.

Step 2: Remove the rear turn signal bulb socket

• Reach through the opening and locate the turn signal bulb socket on the back of the taillight.
• Twist the socket counterclockwise by hand to unlock it, then pull it straight out.
• Socket won’t turn? Wiggle gently, don’t force.

Step 3: Replace the bulb

• Put on nitrile gloves and safety glasses.
• Pull the old bulb straight out of the socket (it’s a push-in style).
• Push the new rear turn signal bulb (7440 amber) straight into the socket until fully seated.
• Don’t touch the bulb glass with bare fingers.

Step 4: Reinstall the socket and close up

• Insert the socket back into the taillight and twist clockwise by hand until it locks.
• Reinstall the access cover and any clips using the plastic trim removal tool as needed.

Step 5: Repeat on the other side

• Do the same procedure on the opposite rear taillight so both turn signals match.
