🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct bulb socket

• Open the hood and look behind the headlight on the side you’re replacing.
• Use a flashlight to locate the turn signal socket (it’s usually the amber/outer-side bulb area).
• If access is tight, work by feel.

Step 2: Remove the turn signal bulb socket

• Grip the socket firmly by hand.
• Rotate the socket counterclockwise about 1/4 turn to unlock it.
• Pull the socket straight out of the headlight housing.

Step 3: Remove the old bulb

• Pull the old bulb straight out of the socket (it’s a push-in style).
• If it’s stuck, gently wiggle while pulling—do not twist hard.

Step 4: Install the new bulb

• With nitrile gloves on, push the new 7440A amber bulb straight into the socket until fully seated.
• If you accidentally touch the glass, wipe it clean with a dry, lint-free cloth before installing.

Step 5: Reinstall the socket

• Insert the socket back into the headlight housing, lining up the tabs.
• Rotate the socket clockwise about 1/4 turn until it locks.
• Make sure it feels secure and doesn’t wobble.

Step 6: Repeat on the other side

• Replace the other front turn signal bulb the same way.
• Matching bulbs look more even.

✅ After Repair
