📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
• Turn the steering wheel away from the side you’re working on (this gives more hand room in the wheel well).
• If you want extra space, you can lift that front corner using a floor jack and support with jack stands.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Make room in the front wheel well

• Turn the wheel so the tire points away from the side you’re servicing.
• If lifting: place the floor jack at the front jacking point, raise the car, then support it with jack stands.

Step 2: Open the fender liner access

• Use a trim clip remover to pop out the plastic push clips holding the small access flap in the front portion of the fender liner.
• If your liner uses screws/bolts instead, remove them with a Phillips screwdriver #2 or 10mm socket and 1/4" drive ratchet.
• Peel the liner/flap back carefully to see behind the headlight. Use a flashlight.

Step 3: Remove the turn signal bulb socket

• Find the turn signal socket on the back of the headlight housing (it will have a wiring connector going into a twist-lock socket).
• Grip the socket and rotate it counterclockwise by hand, then pull it straight out.
• Wiggle gently; don’t yank the wires.

Step 4: Replace the bulb

• Put on nitrile gloves.
• Pull the old bulb straight out of the socket.
• Push the new 7440/7440NA amber bulb straight into the socket until fully seated.

Step 5: Reinstall the socket and close the liner

• Insert the socket back into the headlight housing and rotate clockwise until it locks.
• Reposition the liner access flap and reinstall the clips using the trim clip remover (or reinstall fasteners with a Phillips screwdriver #2 / 10mm socket and 1/4" drive ratchet).

Step 6: If you lifted the car, set it back down

• Raise slightly with the floor jack, remove the jack stands, then lower the car slowly.
• Remove the wheel chocks after the car is fully on the ground.
