🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open trunk and move trunk trim aside (left side)

• Use your hands to gently pull back the fabric trunk liner on the left side, near the taillight area.
• If any plastic clips hold the liner, use the trim removal tool to gently pry the clip centers up, then remove the clips.
• If needed, use the small flathead screwdriver to lift the clip center slightly, then switch to the trim tool. Work slowly to avoid breaking clips

Step 2: Remove taillight mounting nuts (left side)

• Locate the metal studs with nuts holding the taillight to the body (usually 2 nuts) behind the liner.
• Use the 10mm socket, 1/4" ratchet, and extension to remove the nuts.
• Keep the nuts in a safe place so they don’t fall into the trunk or bumper.
• Torque on reassembly: 5 Nm (44 in-lbs)

Step 3: Remove the taillight assembly from the body (left side)

• From outside the car, place one hand on the side of the taillight and the other on the rear face.
• Gently pull the taillight straight back away from the body; there are locating pins that will pop free.
• If it feels stuck, wiggle gently while pulling straight back. Do not pry with metal tools
• Once loose, support the taillight with one hand so it doesn’t drop or scratch the paint.

Step 4: Disconnect bulb socket and remove old bulb (left side)

• On the back of the taillight, find the bulb socket for the tail/brake bulb (it’s the larger dual-filament bulb, usually near the center of the housing).
• Twist the socket counterclockwise by hand about a quarter turn and pull it straight out of the taillight.
• Pull the old bulb straight out of the socket using a gentle rocking motion.
• If it’s stuck, use the clean microfiber cloth in your fingers for better grip.

Step 5: Install the new taillight bulb (left side)

• With gloves on, take a new 7443 dual-filament bulb and push it straight into the socket until fully seated.
• If you touch the glass with bare fingers, clean it with an alcohol wipe and let it dry. Oil can shorten bulb life
• Optional: Apply a very thin smear of dielectric grease to the bulb base contacts, not the glass.
• Reinsert the bulb and socket into the taillight housing, then twist clockwise until it locks in place.

Step 6: Quick test of the left taillight

• Gently rest the taillight in position (don’t bolt it yet, just hold or let it sit carefully).
• Ask a helper to turn the ignition to ON and switch on the parking lights, then press the brake pedal.
• Check that the left taillight is on for running light and gets brighter when the brake is pressed.
• Turn the lights off again before continuing.

Step 7: Reinstall the left taillight assembly

• Align the plastic guide pins on the taillight with the holes in the body.
• Push the taillight straight in until it sits flush with the body panel.
• Inside the trunk, reinstall the 10mm nuts by hand first to avoid cross-threading.
• Use the 10mm socket and ratchet to tighten each nut snugly.
• Torque to 5 Nm (44 in-lbs) – just a firm, light tighten, not “gorilla tight.”

Step 8: Reinstall trunk trim on the left side

• Fold the trunk liner back into its original position.
• Reinstall any trim clips: push the clip body in first, then press the center pin in until it sits flush.
• Check that the liner is not pinched under the taillight studs or wiring.

Step 9: Repeat steps 1–8 for the right side

• Follow the exact same process on the right side of the trunk and taillight.
• Use the same 10mm socket, ratchet, and trim tool to remove nuts and clips.
• Install the second new 7443 bulb on the right side.
• Torque right-side nuts to 5 Nm (44 in-lbs).

Step 10: Final test of both taillights

• Close the trunk gently.
• Turn ignition to ON, switch on the parking lights, and walk behind the car to confirm both taillights are evenly lit.
• Press and hold the brake pedal (or have a helper do it) and confirm both sides get brighter.
• If either side doesn’t work, recheck the bulb seating and socket twist position.

✅ After Repair

• 🧪 Check all rear lights: tail, brake, turn signals, and reverse, so you know everything is working.
• 🚗 Take a short drive at dusk and have someone follow you to confirm brightness and visibility.
• 🧴 If you used dielectric grease, wipe any extra from outside the sockets so it doesn’t attract dust.
