🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the headlamp area

• Open the hood and locate the rear of the headlamp housing.
• If the air duct or washer bottle neck blocks access, use a 10mm socket or flat-blade screwdriver to loosen the nearby fasteners or clips as needed.
• Move the part aside gently for working room.

Step 2: Remove the bulb socket

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

Step 3: Remove the old bulb

• Press the bulb release tab, if equipped, and remove the bulb from the socket.
• If the bulb is tight, use a flat-blade screwdriver carefully to help release the retaining tabs.
• Compare the old bulb to the new one to confirm the same fit.

Step 4: Install the new bulb

• Put on gloves and install the new bulb into the socket.
• Make sure it seats fully and locks in place.
• Do not touch the glass part of the bulb.

Step 5: Reinstall the socket

• Insert the bulb and socket back into the headlamp housing.
• Twist clockwise by hand until it locks.
• Repeat the same steps on the other side.

Step 6: Test the lights

• Turn the headlights on and confirm both bulbs work.
• Check low beam and high beam operation if you replaced both front bulbs.
• Make sure the beam pattern looks even from side to side.
