🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify which “taillight bulbs” you’re replacing

• Each outer taillamp can contain more than one bulb (tail/brake, turn signal, reverse), depending on equipment.
• Before removing anything, turn the lights on and press the brake (have a helper) to confirm which bulb is out on each side.
• Replace bulbs in pairs for even brightness.

Step 2: Remove the left taillamp fasteners

• At the inboard edge of the left taillamp (liftgate open), remove the fasteners using a Torx T30 screwdriver.
• If your lamp uses nuts instead, remove them with a 10mm socket, 1/4" drive ratchet, and 3" extension.

Step 3: Pull the left taillamp housing straight back

• Hold the lamp with both hands and pull it straight rearward to release the locating pins.
• If it’s stuck, gently work the edge with a plastic trim removal tool set.
• Do not pry hard—pins can snap.

Step 4: Remove the left bulb socket(s)

• Find the round bulb socket(s) on the back of the lamp.
• Twist the socket counterclockwise by hand and pull it out.
• If there’s only a large electrical connector and no twist sockets, your lamp may be LED and the bulbs may not be serviceable (lamp replacement required).

Step 5: Replace the left bulb(s)

• Pull the old bulb straight out of the socket (or twist it out if it’s a twist-lock style).
• Match the bulb number printed on the old bulb base to the new bulb.
• Install the new bulb using nitrile gloves.
• If available, apply a tiny amount of dielectric grease (optional) to the rubber seal of the socket.

Step 6: Reinstall the left bulb socket(s) and lamp

• Insert the socket back into the housing and twist clockwise until it locks.
• Align the lamp locating pins with the body and press the lamp straight in until it sits flush.

Step 7: Tighten the left taillamp fasteners

• Reinstall fasteners with a Torx T30 screwdriver or 10mm socket (whichever your lamp uses).
• Torque to 3 Nm (27 in-lbs).

Step 8: Repeat Steps 2-7 on the right taillamp

• Use the same Torx T30 screwdriver or 10mm socket to remove the right-side fasteners.
• Pull the right taillamp straight back, swap the bulb(s), and reinstall.

Step 9: Function test both sides

• Turn on parking lights and verify both taillights illuminate evenly.
• Press the brake pedal (helper) and verify both brake lights work.
• Test turn signals, hazards, and reverse lights.

✅ After Repair

• Confirm both lamps are seated flush and gaps are even.
• Verify no warning messages are present on the dash.
• If a bulb still doesn’t work, remove the socket and re-seat it firmly; also check the bulb is fully seated in the socket.
