⚠️ Safety & Precautions

• Turn the lights off and let the bulb cool before touching it.
• Use a jack and jack stands if you need extra wheelhouse access. Never rely on the jack alone.
• Do not touch the glass of the new bulb with bare fingers if it is a halogen bulb. Skin oils can shorten bulb life.
• If you are working near the wheel, keep hands clear of sharp splash shield edges.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the front of the wheel opening

• Turn the front wheels away from the side you are replacing to create more room.
• If needed, use the floor jack and jack stands for better access.
• More room makes the job easier.

Step 2: Remove the splash shield fasteners

• Use the 10mm socket and ratchet to remove the fasteners holding the small front wheelhouse splash shield section.
• If your Sienna uses clip-style retainers in that area, use the trim clip removal tool to release them.
• Pull the shield back enough to reach the back of the turn signal bulb socket.

Step 3: Remove the bulb socket

• Locate the turn signal bulb socket at the back of the headlamp assembly.
• Twist the socket counterclockwise by hand and pull it straight out.
• Do not force it.

Step 4: Replace the bulb

• Remove the old bulb from the socket by pulling it straight out.
• Install the new front turn signal bulb into the socket.
• If the bulb is glass halogen, handle it with gloves.

Step 5: Reinstall the socket

• Insert the socket back into the headlamp housing.
• Twist it clockwise until it locks in place.
• Make sure it is seated fully so moisture cannot get in.

Step 6: Reinstall the splash shield

• Put the splash shield back in position.
• Reinstall the fasteners using the 10mm socket and ratchet, or snap the clips back in with the trim clip removal tool if needed.
• Check for any loose clips.

Step 7: Test the turn signal

• Turn the ignition on and activate the front turn signal.
• Check for proper flashing and confirm the bulb is working.

✅ After Repair

• Walk around the Sienna and confirm both front turn signals flash normally.
• If the new bulb does not work, recheck that the socket is fully locked in.
• If the turn signal flashes fast, the bulb may not be seated correctly or the wrong bulb type may be installed.
