🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the bulb socket

• Open the hood and find the back side of the headlamp assembly.
• Look for the turn signal bulb socket near the outer corner of the lamp.

Step 2: Remove the bulb socket

• Use your hand to twist the socket counterclockwise and pull it out of the headlamp housing.
• If it is tight, use a flat blade trim tool gently to help release the retaining tab.
• Twist, then pull straight out.

Step 3: Remove the old bulb

• Pull the old bulb straight out of the socket.
• If needed, use needle-nose pliers carefully to grip the base, not the glass.

Step 4: Install the new bulb

• Push the new bulb into the socket until it seats fully.
• Do not touch the glass if it is a halogen bulb.

Step 5: Reinstall the socket

• Line up the socket tabs with the headlamp opening.
• Push it in and twist clockwise until it locks.
• No torque spec applies to this bulb socket.

Step 6: Test the new bulb

• Turn the ignition on and check the front turn signal.
• Verify both the left and right signals flash correctly.
• Also check the parking light function if the bulb shares that circuit.

✅ After Repair
