🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open access to the headlamp area

• Open the hood.
• If the washer bottle neck or intake duct blocks your hand, use the 7mm socket and 1/4-inch ratchet to remove any small access fasteners in the way.
• Keep fasteners in a tray.

Step 2: Remove the bulb socket

• Reach behind the headlamp housing and find the front turn signal bulb socket.
• Twist the socket counterclockwise by hand to unlock it.
• Pull the socket straight out of the housing.

Step 3: Replace the bulb

• Press the old bulb into the socket, then twist it out if your socket uses a twist-lock bulb.
• Install the new bulb by hand until it seats fully.
• Match the bulb base exactly.

Step 4: Reinstall the socket

• Insert the bulb socket back into the headlamp housing.
• Twist it clockwise by hand until it locks.
• Make sure it sits fully seated to prevent moisture intrusion.

Step 5: Reassemble any removed access parts

• If you removed any intake duct or access fasteners, reinstall them using the 7mm socket and 1/4-inch ratchet.
• Snug them only; do not overtighten plastic fasteners.
