🔧 Regal - Front Turn Signal Bulb Replacement

You’ll be accessing the back of each front headlamp housing and swapping the turn signal bulb. This is usually done through the front wheel-well liner, so you don’t need to remove the bumper or headlight.

Assumption: Your Regal uses an amber wedge-base front turn signal bulb (commonly 7440NA/7444NA); some headlamp options can vary.

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

⚠️ Safety & Precautions

• 🛑 Support the car with jack stands before working in the wheel well.
• Let the headlamp area cool; bulbs and housings can get hot.
• Do not touch the glass of a halogen bulb with bare fingers; skin oils can shorten bulb life.
• Keep the key off and lights off while swapping bulbs.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the front wheel lug nuts

• Use a 19mm socket with a 1/2" drive ratchet to loosen the lug nuts about 1/2 turn (do not remove yet).

Step 2: Safely lift and support the front corner

• Lift the front corner with a floor jack at the proper jacking point.
• Set the car onto jack stands and give the car a gentle push to confirm it’s stable.

Step 3: Remove the front wheel

• Use a 19mm socket and 1/2" drive ratchet to remove the lug nuts.
• Remove the wheel and set it flat under the car as an extra safety backup.

Step 4: Open the front wheel-well liner access

• Use a 7mm socket with a 1/4" drive ratchet to remove the small screws along the front portion of the wheel-well liner (the section closest to the headlamp).
• Use a trim clip removal tool (a forked tool that pops plastic fasteners out) to remove any plastic push-clips holding the liner edge.
• If a clip is stubborn, use a flathead screwdriver to gently pry the center up first, then remove the clip.
• Pull the liner back just enough to reach behind the headlamp. Use a flashlight to see the bulb sockets.

Step 5: Remove the turn signal bulb socket

• Locate the turn signal socket on the back of the headlamp (you’ll see wiring going to a twist-lock socket).
• Grip the socket firmly with nitrile gloves and rotate it about 1/4 turn counterclockwise, then pull it straight out.
• If tight, wiggle gently—don’t yank the wires.

Step 6: Replace the bulb

• Pull the old bulb straight out of the socket (it’s a push-in “wedge” style).
• Install the new amber bulb by pushing it straight into the socket until fully seated.
• Do not touch the bulb glass; keep nitrile gloves on.

Step 7: Reinstall the socket and test

• Insert the socket back into the headlamp and rotate clockwise about 1/4 turn until it locks.
• Before reassembling the liner, turn the ignition on and test the turn signal and hazards.
• If it doesn’t light, turn everything off, remove the socket, and re-seat the bulb fully.

Step 8: Reinstall the wheel-well liner

• Reposition the liner and reinstall screws using a 7mm socket and 1/4" drive ratchet.
• Reinstall push-clips using a trim clip removal tool to align them, then press them in by hand.

Step 9: Reinstall the wheel and torque lug nuts

• Reinstall the wheel and hand-thread all lug nuts.
• Snug them using a 19mm socket and 1/2" drive ratchet in a star pattern.
• Lower the car off the jack stands using the floor jack.
• Final-tighten with a 1/2" drive torque wrench: Torque to 140 Nm (103 ft-lb) in a star pattern.

Step 10: Repeat on the other side

• Repeat Steps 1-9 for the opposite front turn signal bulb.
• Replace in pairs for matching brightness and color.

✅ After Repair

• Test left and right turn signals and the hazard flashers.
• Confirm the turn signal “click” speed is normal (fast flashing usually means a bulb isn’t working).
• Make sure the wheel-well liner is fully secured so it can’t rub the tire.
