🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the trunk and find the rear trim clips

• Use the shop light to look at the trunk liner behind the left taillight.
• Locate the plastic push clips holding the trunk side trim in place.
• The taillight bulb sockets sit behind this trim panel.

Step 2: Remove the left-side trunk trim clips

• Use the trim clip removal tool to gently pry out the plastic clips from the left rear trunk liner.
• If a clip is stubborn, use needle-nose pliers to grip the center pin and pull it outward carefully.
• Pull the trunk liner back just enough to reach the taillight bulb sockets.
• Do not crease the liner.

Step 3: Identify the taillight bulb socket

• Use the shop light to view the bulb sockets on the back of the taillight housing.
• The taillight bulb socket is the socket connected to the rear running light circuit.
• A bulb socket is the plastic holder that locks the bulb into the taillight housing.

Step 4: Remove the left taillight bulb socket

• Grip the taillight bulb socket by hand while wearing clean nitrile gloves.
• Turn the socket counterclockwise about a quarter turn.
• Pull the socket straight out of the taillight housing.
• No torque spec applies; the socket is hand-tight only.

Step 5: Replace the left taillight bulb

• Pull the old bulb straight out of the socket by hand while wearing clean nitrile gloves.
• Push the new rear taillight bulb straight into the socket until it seats fully.
• If the bulb is a wedge-style bulb, it only pushes in; do not twist it.
• Handle only the plastic base.

Step 6: Reinstall the left taillight bulb socket

• Insert the socket back into the taillight housing by hand.
• Turn the socket clockwise until it locks in place.
• Make sure the socket sits flat and does not wiggle.
• No torque spec applies; the socket locks by hand.

Step 7: Repeat on the right side

• Use the trim clip removal tool to remove the right-side trunk trim clips.
• Use the shop light to locate the right taillight bulb socket.
• Turn the socket counterclockwise by hand and pull it out.
• Pull the old bulb straight out while wearing clean nitrile gloves.
• Push the new rear taillight bulb fully into the socket.
• Reinstall the socket and turn it clockwise until it locks.

Step 8: Test both taillights before closing the trim

• Turn the headlight switch to the parking light or headlight position.
• Walk to the rear and confirm both taillights glow evenly.
• If one does not work, turn the lights off and use clean nitrile gloves to remove and reseat that bulb.
• Test before reinstalling clips.

Step 9: Reinstall the trunk trim

• Push the trunk liner back into its original position by hand.
• Reinstall each plastic clip by pressing it into place by hand.
• If needed, use needle-nose pliers to align a clip before pushing it in.
• Do not overtighten or force clips; no torque spec applies.
