• Use the parking brake and keep the key off.
• If you need extra room, disconnect the negative battery cable before working near the harness.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and find the headlight access covers

• Open the hood and locate the rear of each headlight assembly.
• Find the round or capped access cover behind the low-beam bulb.
• Take a quick photo before removing parts.

Step 2: Make room on the driver side if needed

• If your hand space is tight, use the 10mm socket, 1/4-inch ratchet, and short extension to remove the intake duct fasteners.
• Lift the duct out carefully and set it aside.
• This gives you room to reach the bulb socket.

Step 3: Remove the bulb access cover

• Turn the cover counterclockwise by hand, or release the tabs if equipped.
• Pull the cover straight off and set it aside cleanly.
• Keep dirt out of the headlight housing.

Step 4: Remove the old bulb

• Unplug the bulb connector by pressing the release tab and pulling straight back.
• Release the bulb from the headlight housing by turning it counterclockwise.
• Pull the bulb out carefully without forcing it.

Step 5: Install the new bulb

• Put on gloves before handling the new bulb.
• Insert the new bulb into the housing in the same position as the old one.
• Turn it clockwise to lock it in place.
• Reconnect the bulb connector until it clicks.
• Do not touch the glass.

Step 6: Reinstall the access cover

• Set the cover back in place and turn it clockwise, or press the tabs fully closed.
• Make sure the seal sits evenly so moisture stays out.

Step 7: Repeat on the other side

• Repeat the same process for the second bulb.
• Use the same tools and the same fitment steps.

Step 8: Reinstall the intake duct if removed

• Put the duct back in place.
• Reinstall the 10mm fasteners and snug them down.
• Do not overtighten the plastic parts.
