🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the tail lamp bulb area from the trunk

• Open the trunk and look behind the tail lamp area on the side you’re replacing.
• Use a flashlight to find the small access cover or trunk liner flap near the tail lamp.
• If there are plastic clips holding the liner, gently pry them with a plastic trim removal tool.
• If a screw is present on the access cover, remove it with a Phillips #2 screwdriver.

Step 2: Identify the turn signal bulb socket

• Look for the bulb sockets going into the tail lamp housing.
• The turn signal socket is usually one of the larger twist-lock sockets.
• If unsure, turn hazards on to confirm.

Step 3: Remove the bulb socket

• Grip the socket firmly and rotate it counterclockwise about 1/8 to 1/4 turn.
• Pull the socket straight out of the tail lamp housing.

Step 4: Remove the old bulb

• Pull the old bulb straight out of the socket (it’s a push-in style on this setup).
• If it feels stuck, gently wiggle while pulling—don’t crush the glass.

Step 5: Install the new bulb

• Using nitrile gloves, push the new bulb straight into the socket until fully seated.
• Make sure it sits straight (crooked seating can cause flickering or no operation).

Step 6: Reinstall the socket

• Insert the socket back into the tail lamp housing.
• Rotate clockwise until it locks in place.

Step 7: Reinstall the trunk liner/access cover

• Reposition the trunk liner.
• Reinstall any clips by pressing them in by hand.
• If removed, tighten the access cover screw with a Phillips #2 screwdriver (snug, do not overtighten).

Step 8: Repeat on the other side

• Repeat the same steps for the opposite rear turn signal.
• Replacing in pairs keeps brightness even.

✅ After Repair

• ✅ Turn hazards ON and walk around the car to confirm both rear signals flash evenly.
• ✅ If the turn signal flashes fast, that usually means a bulb isn’t working—recheck bulb seating and socket lock.
