🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm you’re replacing the correct bulb

• Turn the ignition to ON (engine not needed).
• Turn on the left/right turn signal and confirm which side is out.
• Turn ignition OFF again before working.

Step 2: Access the tail lamp bulb socket from the trunk

• Use a flashlight to find the rear of the tail lamp inside the trunk.
• Remove the trunk side access cover/liner near the tail lamp using a plastic trim removal tool.
• If there are plastic push-clips, gently pry the center pin out with the trim removal tool, then pull the clip out.

Step 3: Remove the rear turn signal bulb socket

• Locate the bulb socket for the turn signal (typically the amber bulb position).
• Grip the socket and rotate it counterclockwise about 1/4 turn, then pull it straight out.
• If it’s tight, wiggle gently—don’t yank.

Step 4: Replace the bulb

• Wear nitrile gloves.
• Pull the old bulb straight out of the socket (single-filament wedge/push type for this position).
• Push the new rear turn signal bulb (amber, single-filament) straight into the socket until fully seated.

Step 5: Reinstall the socket and test

• Insert the socket back into the tail lamp housing.
• Rotate clockwise to lock it in place.
• Turn ignition ON and test: left signal, right signal, and hazards.

Step 6: Reinstall trunk trim

• Reinstall the access cover/liner.
• Reinstall any push-clips by pushing the clip body in first, then press the center pin in using a Phillips #2 screwdriver handle or your thumb.

Step 7 (If your turn signal is not a twist-out socket): Remove the tail lamp assembly

• If you don’t see a twist-out socket, remove the tail lamp to reach the bulb carrier.
• Remove the inner trim more fully as needed using a plastic trim removal tool.
• Remove tail lamp retaining nuts using a 10mm socket, 1/4" ratchet, and 3" extension.
• Pull the tail lamp straight rearward to release the locating pins (do not pry against painted body).
• Disconnect the connector, access the bulb holder, replace the bulb, then reinstall.
• When tightening the lamp nuts: Torque to 7–9 Nm (62–80 in-lbs).

✅ After Repair

• Verify both rear turn signals flash at a normal rate (not “fast flash”).
