• ⚠️ Bulbs can be hot—let them cool for 5-10 minutes.
• ⚠️ Don’t touch the new bulb glass with bare fingers; oil can shorten bulb life. Use gloves or a clean paper towel.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the liftgate and locate the taillamp screws

• Open the liftgate and look at the inner edge of the taillamp (the side facing the liftgate opening).
• You’ll see the retaining screws for the lamp housing.

Step 2: Remove the taillamp housing

• Use a Phillips #2 screwdriver to remove the taillamp retaining screws.
• Set the screws aside where they won’t fall or get lost.
• Grip the lamp housing and pull it straight rearward to release the alignment pins.
• If it’s stuck, use a plastic trim removal tool to gently help it start moving. Pull straight back to avoid breaking pins.

Step 3: Remove the taillight bulb socket

• Behind the housing, find the bulb socket for the taillight function (typically the larger dual-filament bulb for tail/brake).
• Twist the socket counterclockwise about a quarter turn by hand, then pull it out.

Step 4: Replace the bulb

• Put on nitrile gloves (or use a clean paper towel).
• Pull the old bulb straight out of the socket (wiggle gently if needed).
• Push the new bulb straight into the socket until fully seated.

Step 5: Reinstall the socket and lamp housing

• Insert the socket back into the lamp and twist clockwise to lock it.
• Line up the housing’s locating pins with the body grommets, then push the housing straight forward until it seats flush.
• Reinstall the screws using the Phillips #2 screwdriver and snug them evenly: Torque to 2-3 Nm (18-27 in-lbs).

Step 6: Repeat on the other side

• Repeat Steps 1-5 for the opposite taillamp so both bulbs are replaced as a matched pair.

✅ After Repair

• Press the brake pedal (or have a helper press it) and confirm both brake lights work.
• Turn on the hazards and confirm both sides flash normally (not fast).
• Check the lamp housings sit flush and don’t wiggle (prevents water leaks).
