• ⚠️ Turn the lights OFF and remove the key before starting.
• ⚠️ Let bulbs cool first; they can burn you.
• ⚠️ Don’t touch a new glass bulb with bare fingers; oil can shorten bulb life.
• ⚠️ Support the lamp as you pull it out so it doesn’t scratch paint.
• Battery disconnect is not required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which bulbs you’re replacing

• Turn the lights on briefly to identify what’s out (tail/running, brake, turn signal, reverse), then turn everything OFF.
• If unsure, I can map each socket position.

Step 2: Remove the driver-side taillight assembly

• With the tailgate open, locate the two lamp fasteners on the inner edge of the driver-side taillight.
• Remove them using a #2 Phillips screwdriver (if yours uses bolts instead, use a 10mm socket with a 1/4" drive ratchet).
• Pull the lamp straight rearward to release the alignment pins. If it’s stuck, use a trim removal tool gently at the edge and wiggle the lamp out.

Step 3: Remove the bulb socket(s)

• Turn the bulb socket you need counterclockwise and pull it straight out of the lamp.
• Use a flashlight to confirm you’re on the correct socket.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new bulb fully into the socket.
• Wear nitrile gloves so you don’t contaminate a glass bulb.

Step 5: Reinstall the socket(s)

• Insert the socket into the lamp and turn it clockwise until it locks.
• Make sure the socket is fully seated (a loose socket can cause moisture inside the lamp).

Step 6: Reinstall the taillight assembly

• Align the lamp’s locating pins and push the lamp straight into place.
• Reinstall the two fasteners using a #2 Phillips screwdriver (or 10mm socket if equipped).
• Torque to 3.5 Nm (31 in-lbs) using a torque wrench (inch-pound).

Step 7: Repeat on the passenger side

• Repeat Steps 2 through 6 for the passenger-side taillight.
• Replace the same bulb type on both sides.

Step 8: Test all rear lights

• Test running lights, brake lights, turn signals, and reverse lights.
• Have a helper press the brake pedal, or back up near a wall to see light output.

✅ After Repair

• If a bulb doesn’t work, remove that socket and reseat the bulb fully, then check the socket is locked.
• If you see condensation later, recheck that each socket is fully seated and locked.
