⚠️ Safety & Precautions

• ⚠️ Turn the ignition OFF and set the parking brake before working near the cooling fan and belts.
• ⚠️ Let the headlamps cool down first; bulbs and housings can be hot.
• ⚠️ Don’t touch the new bulb glass with bare fingers; skin oils can shorten bulb life.
• ⚠️ Battery disconnect is not required, but keep keys out of the car so lights can’t be switched on accidentally.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify the correct bulb socket

• Use a flashlight and look behind the headlamp assembly.
• Find the turn signal socket (it’s the socket that twists out; wiring plugs into it).
• If space is tight, remove a nearby duct/neck.

Step 2: Create working room (Passenger side, if needed)

• Loosen the intake duct clamp using a 7mm socket, 1/4" ratchet, and 6" extension for 1/4" ratchet.
• If your duct uses push clips, pop them out with a trim clip removal tool (a small forked tool that pulls plastic clips without breaking them).
• Move the duct slightly aside to reach the bulb socket.

Step 3: Create working room (Driver side, if needed)

• Locate the washer fluid filler neck near the headlamp area.
• Remove the retaining bolt using a 10mm socket, 1/4" ratchet, and 6" extension for 1/4" ratchet.
• Pull the filler neck up/out of its grommet just enough to access the bulb socket.
• If reinstalling a bolt, Torque to 9 Nm (80 in-lbs).

Step 4: Remove the turn signal bulb socket

• Grip the socket firmly and rotate it counterclockwise by hand.
• Pull the socket straight out of the headlamp housing.

Step 5: Replace the bulb

• Wear nitrile gloves to keep oils off the bulb.
• Pull the old bulb straight out of the socket (no twisting for most 7440-style bulbs).
• Push the new amber 7440A / 7440NA bulb straight into the socket until fully seated.

Step 6: Reinstall the socket

• Insert the socket back into the headlamp opening.
• Rotate clockwise by hand until it locks snugly.
• Make sure the socket O-ring area sits flush so moisture can’t get in.

Step 7: Reinstall anything you moved

• Reposition the intake duct and tighten the clamp with a 7mm socket, 1/4" ratchet, and 6" extension for 1/4" ratchet.
• Reinstall any push clips using a trim clip removal tool to align them, then press them in by hand.
• Re-seat the washer filler neck and reinstall the bolt using a 10mm socket; Torque to 9 Nm (80 in-lbs).

✅ After Repair

• Turn the ignition to ON and test left and right turn signals.
• Turn on hazard lights and walk around the car to confirm both front signals flash evenly.
• If a bulb doesn’t work, remove it and re-seat it fully in the socket.
• Make sure any ducts/neck you moved are secure and not rubbing a belt or fan.
