🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the tail lamp fasteners

• Open the tailgate and locate the two Phillips screws on the inside edge of the tail lamp.
• Use a Phillips #2 screwdriver to remove both screws.

Step 2: Remove the tail lamp housing

• Grip the lamp housing with both hands.
• Pull the lamp straight back to release the alignment pins (no twisting).
• If it’s stuck, use a plastic trim removal tool (a plastic wedge used to separate panels without scratching paint) and gently help it pop free from the rear edge.

Step 3: Remove the rear turn signal bulb socket

• Identify the turn signal socket on the back of the lamp (the one that matches the turn-signal position in the lens).
• Use your hand to rotate the socket counterclockwise about 1/4 turn, then pull it out.
• Use a small flashlight if you need help seeing the socket orientation.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket by hand.
• Install the new bulb by pressing it straight in until fully seated.
• Apply a thin wipe of dielectric grease to the socket seal (not on the bulb glass). Keeps water out and prevents corrosion.

Step 5: Reinstall the socket and test

• Insert the socket back into the lamp and rotate clockwise to lock it.
• Before reinstalling the lamp, turn the hazards ON to confirm the bulb flashes.
• If it doesn’t light, turn hazards OFF and re-seat the bulb and socket.

Step 6: Reinstall the tail lamp housing

• Align the lamp’s pins with the body grommets, then push the lamp straight in until it seats flush.
• Install the two screws using a Phillips #2 screwdriver and tighten snug (do not overtighten; the lamp can crack).
