📋 Before You Begin

• Park on level ground and set the parking brake.
• Open the liftgate for access to the tail lamp fasteners.
• Quick check: if you can remove a twist-in socket from the back of the tail lamp, you have a replaceable bulb. If the turn signal area looks fully sealed with no socket access, it’s likely LED and the lamp assembly must be replaced.
• Tip: Replace both sides for matching brightness.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the tail lamp fasteners

• Open the liftgate and use a flashlight to look at the inboard edge of the tail lamp.
• Remove any small trim covers (if equipped) using a trim removal tool.

Step 2: Remove the tail lamp from the body

• Remove the visible fasteners at the liftgate opening using a Phillips screwdriver or 10mm socket (varies by lamp).
• Gently pull the tail lamp straight rearward to release the alignment pins.
• If it feels stuck, use a trim removal tool to help start it, then pull by hand.
• Tip: Pull straight back, don’t twist the lamp.

Step 3A: If equipped with a replaceable bulb (most common setup)

• Locate the turn signal bulb socket on the back of the lamp (it will be a twist-lock socket).
• Twist the socket counterclockwise by hand; if tight, use a nitrile-gloved grip or a small pick tool to help start the twist.
• Pull the socket out.
• Remove the old bulb by pulling it straight out of the socket.
• Install the new bulb by pushing it straight in until fully seated.
• Apply a tiny amount of dielectric grease to the socket seal (not on the bulb glass).
• Reinstall the socket and twist clockwise until it locks.

Step 3B: If your turn signal is LED (no bulb socket)

• Disconnect the tail lamp electrical connector by pressing the tab and pulling apart by hand.
• Install the new tail lamp assembly and reconnect the electrical connector until it clicks.

Step 4: Reinstall the tail lamp

• Line up the alignment pins with the body and push the lamp straight in by hand until fully seated.
• Reinstall the fasteners using a Phillips screwdriver or 10mm socket and tighten snugly (do not overtighten).
• Reinstall any trim covers using a trim removal tool.

✅ After Repair

• Turn the vehicle ON (READY not required) and test left and right rear turn signals.
• Check the hazard lights to verify both rear turn signals flash evenly.
• If you get fast flashing (hyperflash) or a bulb-out message, recheck the bulb seating and the lamp connector.
• Make sure the tail lamp sits flush with the body and the liftgate closes without contact.
