• ⚠️ If the tail lamp was recently on, let it cool for a few minutes.
• ⚠️ Don’t touch the glass of a new bulb with bare fingers; oils can shorten bulb life.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the tail lamp from inside the trunk

• Open the trunk and use a flashlight to locate the trunk liner behind the tail lamp on the side you’re replacing.
• Use a plastic trim clip removal tool to pop out the plastic push-clips holding the liner.
• If a clip is tight, gently help it with a small flat-blade screwdriver while pulling with the trim tool. Go slow to avoid breaking clips.
• Pull the liner back enough to reach the bulb sockets on the rear of the tail lamp.

Step 2: Identify the rear turn signal socket

• Put on nitrile gloves and safety glasses.
• Use the flashlight to find the bulb socket that corresponds to the turn signal (the one that flashes amber when signaling).
• If you’re unsure which socket it is, turn the hazard lights ON briefly, then OFF, and watch which section of the tail lamp flashes to help you confirm the correct location.

Step 3: Remove the turn signal bulb socket

• Grip the socket firmly and rotate it counterclockwise by hand until it unlocks.
• Pull the socket straight out of the tail lamp housing.

Step 4: Replace the bulb

• Remove the old bulb by pulling it straight out of the socket.
• Install the new bulb by pushing it straight in until fully seated. Don’t touch the glass.
• Compare the old bulb and new bulb to confirm the same base and size before installing.

Step 5: Reinstall the socket and trunk liner

• Insert the socket back into the tail lamp housing.
• Twist the socket clockwise until it locks fully.
• Reposition the trunk liner and reinstall the push-clips using the plastic trim clip removal tool to line them up, then press them in by hand.

Step 6: Test the repair

• Turn the ignition ON and test the left/right turn signals and hazard lights.
• Walk behind the car to confirm the replaced side flashes normally (not fast). Fast flashing usually means a bulb issue.

✅ After Repair

• Confirm the bulb flashes at a normal speed on both turn and hazards.
• If it still flashes fast, recheck that the bulb is fully seated and the socket is fully locked.
• If the bulb works intermittently, inspect the socket for corrosion or looseness.
