🔧 Forte - Taillight Bulb Replacement

You’ll replace the rear light bulbs by accessing the bulb sockets from inside the trunk (and, for the trunk-lid lights, behind the trunk lid trim). This restores proper tail/brake/turn/reverse lighting and keeps you legal and safe at night.

Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours

Assumption: Replacing the standard rear bulbs (outer quarter-panel lamp and inner trunk-lid lamp) by matching the bulb number printed on your old bulbs.

⚠️ Safety & Precautions

• ⚠️ Turn the car OFF, remove the key, and make sure lights are OFF before starting.
• ⚠️ Let bulbs cool if they were recently on (they can burn you).
• ⚠️ Wear gloves and avoid touching a new glass bulb with bare fingers (skin oil can shorten bulb life).
• ⚠️ Support the trunk lid so it can’t drop while you’re working.

📋 Before You Begin

• Park on level ground and set the parking brake.
• Open the trunk and remove any cargo so you can reach the side trunk liners.
• Have your replacement bulbs ready and compare them to the old ones (same base and same number printed on the bulb).
• A “trim removal tool” is a plastic pry tool that pops clips out without scratching panels.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the outer taillight bulb area (quarter-panel lights)

• Use a flashlight to look into both rear corners of the trunk.
• Pull back the trunk side lining near the taillight (some cars have a small access flap; if clipped, use a plastic trim removal tool to pop clips gently).

Step 2: Remove the bulb socket from the taillight housing

• Find the round bulb socket(s) going into the back of the taillight.
• Grip the socket and rotate it about 1/4 turn counterclockwise by hand, then pull it straight out.
• Tip: Turn gently; don’t force it.

Step 3: Replace the bulb (outer taillight)

• Remove the old bulb from the socket:
  • If it’s a push-in style: pull straight out.
  • If it’s a twist-lock style: push in slightly and rotate counterclockwise, then pull out.
• Install the new bulb that matches the number printed on the old bulb.
• If the new bulb is glass, use nitrile gloves to keep it clean.

Step 4: Reinstall the socket and repeat on the other side

• Insert the socket back into the housing, making sure the tabs line up.
• Twist clockwise about 1/4 turn until it locks.
• Repeat Steps 1-4 for the other outer taillight.

Step 5: If your “taillight bulbs” are on the trunk lid, access the inner lamp bulbs

• Look at the trunk lid trim panel (the liner on the inside of the trunk lid).
• Use a plastic trim removal tool to pop out the plastic push clips.
• Use a Phillips screwdriver #2 if any screws are present.
• Lower the trim panel enough to reach the bulb sockets for the trunk-lid lamps.

Step 6: Replace trunk-lid lamp bulbs (if equipped)

• Remove the bulb socket by twisting counterclockwise by hand.
• Replace the bulb by matching the number on the old bulb.
• Reinstall the socket by twisting clockwise until locked.

Step 7: Optional: Remove the full taillight assembly only if you can’t remove sockets

• If a socket won’t come out due to space or damage, remove the lamp fasteners from inside the trunk using a 10mm socket, 6" socket extension (1/4" drive), and 1/4" drive ratchet.
• Carefully pull the lamp straight outward (don’t pry the paint).
• Reinstall and tighten fasteners: Torque to 7 Nm (62 in-lbs) using a torque wrench (inch-pound or small Nm) (specialty).

Step 8: Reinstall trunk liners and trim

• Reposition the trunk side liners and press clips back in by hand.
• Reinstall trunk-lid trim clips (replace any broken ones).

✅ After Repair

• Turn the ignition to ON (engine off is fine) and test:
  • Tail lights (parking lights ON)
  • Brake lights (press brake pedal)
  • Turn signals and hazard lights
  • Reverse lights (foot on brake, shift to R)
• If a bulb doesn’t work, remove it and re-seat it fully, then confirm you matched the bulb number and base type.
• Make sure all sockets are fully locked to keep water out of the housing.
