🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify the Correct Bulb Socket

• Use a flashlight or the vehicle’s underhood lighting to look behind the affected headlamp assembly.
• Locate the front turn signal socket at the rear of the headlamp housing. Follow the bulb position from the amber turn signal lens to avoid removing the wrong socket.
• The socket is the plastic holder that locks the bulb into the headlamp housing.

Step 2: Create Access on the Driver Side

• Use both gloved hands to grasp the windshield-washer filler neck.
• Pull the filler neck straight upward to release it from the washer reservoir. Do not twist it against the headlamp housing.
• If a retaining clip limits movement, use the plastic trim removal tool to release it gently.
• Place the filler neck aside without allowing dirt to enter it.
• Cover the opening with a clean glove.

Step 3: Create Access on the Passenger Side

• If your hand reaches the turn signal socket safely, leave the air-cleaner duct installed and continue to Step 4.
• If more room is needed, use the 7mm or 8mm socket, 1/4-inch drive ratchet, and 6-inch extension to loosen the air-cleaner inlet duct fastener fitted to your Impala.
• Use the small flat-blade screwdriver only if the duct has a slotted clamp.
• Move the inlet duct just far enough to reach the socket. Do not disconnect electrical connectors or allow debris into the air intake.
• No turn-signal component is removed during this access step.

Step 4: Remove the Turn Signal Socket

• Use a gloved hand to grasp the turn signal socket by its plastic base.
• Rotate the socket counterclockwise approximately one-quarter turn.
• Pull the socket straight out of the headlamp housing.
• Do not pull on the wiring.
• No tool or torque specification applies to this quarter-turn socket.

Step 5: Remove the Old Bulb

• Hold the socket firmly with one gloved hand.
• Use your other gloved hand to pull the old bulb straight out of the socket.
• If the bulb is stuck, wiggle it gently while pulling. Do not use the screwdriver against the glass.
• Inspect the socket for melted plastic, green corrosion, or burned terminals. A damaged socket must be replaced before installing the bulb.

Step 6: Install the New Bulb

• Keep the nitrile mechanic gloves clean and remove the new 7444NA bulb from its package.
• Align the bulb’s wedge base with the socket and press it straight in until fully seated.
• If bare skin touches the glass, clean it with isopropyl alcohol and allow it to dry completely before installation.
• Replace both sides for matching brightness.

Step 7: Reinstall the Bulb Socket

• Align the socket tabs with the openings in the headlamp housing.
• Push the socket fully into place with a gloved hand.
• Rotate the socket clockwise approximately one-quarter turn until it stops securely.
• Do not use the ratchet on the plastic socket. It is hand-tight only.

Step 8: Restore Driver-Side Access Components

• Use both gloved hands to align the washer filler neck with the reservoir opening.
• Push the filler neck straight down until fully seated.
• If removed, press the retaining clip into place by hand.
• Use the plastic trim removal tool only to guide the clip; do not strike it.

Step 9: Restore Passenger-Side Access Components

• Reposition the air-cleaner inlet duct and confirm it sits evenly without gaps.
• Use the correct 7mm or 8mm socket, ratchet, and extension to tighten its fastener snugly.
• If equipped with a worm-drive clamp, use the small flat-blade screwdriver and tighten only until the duct cannot rotate.
• Do not overtighten the plastic duct or housing. No manufacturer service torque is specified for the removable access duct fastener.

Step 10: Test the New Bulb

• Close the hood before performing the final light test.
• Switch on the ignition and use the turn-signal stalk to test the repaired side.
• Switch on the hazard lamps and verify that both front bulbs flash at equal brightness and speed.
