• Do not touch the glass on a new halogen bulb with bare fingers. Oils can shorten bulb life.
• If the car is in READY mode, shut it down fully before working near the front of the vehicle.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the rear of the headlamp

• Open the hood and locate the rear of the headlamp housing on the side you are replacing.
• If access is tight, use the trim panel removal tool to gently move any plastic retainers or nearby ducting out of the way.
• Work slowly to avoid breaking clips.

Step 2: Remove the bulb socket

• Find the turn signal bulb socket at the back of the headlamp.
• Use your hand to rotate the socket counterclockwise and pull it straight out.
• If it is stuck, use a flat blade screwdriver carefully to start it turning, but do not pry hard.

Step 3: Replace the bulb

• Pull the old bulb straight out of the socket.
• Install the new bulb into the socket until fully seated.
• Make sure the bulb is clean and not touched on the glass.

Step 4: Reinstall the socket

• Insert the socket back into the headlamp housing.
• Rotate it clockwise by hand until it locks in place.
• It should feel snug, not forced.

Step 5: Test the new bulb

• Turn the ignition ON.
• Activate the turn signal for that side.
• Confirm the bulb flashes normally and matches the other side.

✅ After Repair
