🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Secure the Hood

• Use your hand to pull the hood release inside the cabin.
• Use your hand to release the secondary hood latch at the front of the hood.
• Use the hood prop rod to hold the hood open.
• Put on safety glasses and nitrile gloves.

Step 2: Locate the Front Turn Signal Socket

• Use a flashlight to look behind the front corner of the headlamp assembly.
• Find the turn signal socket at the outer side of the lamp housing.
• The socket has wires attached and sits behind the amber front turn signal area.

Step 3: Remove the Socket

• Use your hand to grip the plastic socket body.
• Turn the socket counterclockwise about one-quarter turn.
• Pull the socket straight out of the lamp housing.
• If it feels slippery, use a clean microfiber towel for extra grip.
• Do not twist the wires.

Step 4: Remove the Old Bulb

• Use your gloved fingers to pull the old bulb straight out of the socket.
• If the bulb is stuck, gently wiggle it while pulling straight back.
• If you see dirt or light corrosion, use a small flat-blade screwdriver to gently loosen debris without bending the metal contacts.

Step 5: Install the New Bulb

• Use your gloved fingers to push the new 7440A/7440NA amber bulb straight into the socket.
• Make sure the bulb is fully seated.
• If you touch the bulb with bare fingers, wipe it clean with a clean microfiber towel.
• A fully seated bulb prevents flickering.

Step 6: Reinstall the Socket

• Use your hand to place the socket back into the lamp housing.
• Line up the socket tabs with the slots in the housing.
• Turn the socket clockwise about one-quarter turn until it locks.
• No torque spec is used here because this is a hand-tight twist-lock socket.

Step 7: Test the Bulb

• Use the turn signal stalk to turn on the side you replaced.
• Use the hazard switch to test both front turn signals.
• Walk to the front of your Tacoma and confirm the bulb flashes amber.
• If it does not work, turn the lights OFF, remove the socket, reseat the bulb, and test again.

Step 8: Close the Hood

• Use your hand to place the hood prop rod back in its clip.
• Lower the hood gently.
• Let the hood latch securely from about 8-12 inches above the latch.
• Use your hand to lightly lift the hood and confirm it is fully latched.
