🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the headlamp area

• Open the hood.
• Remove the upper radiator cover fasteners using a 10mm socket and ratchet if they block access to the rear of the headlamp.
• Keep fasteners in a tray.

Step 2: Remove the rear headlamp dust cover

• Reach behind the headlamp assembly and twist off the rear dust cover by hand.
• If tight, gently help it loose with a flat-blade trim tool.
• Set the cover aside where it stays clean.

Step 3: Remove the old bulb

• If halogen: unplug the electrical connector by pressing the lock tab and pulling it straight off.
• If HID/xenon: disconnect the igniter connector first, then release the bulb retainer.
• Rotate the bulb counterclockwise if the design uses a twist-lock base, or release the spring clip if equipped.
• Pull the bulb straight out.

Step 4: Install the new bulb

• Insert the new bulb into the socket in the same orientation as the old one.
• Do not touch the glass on halogen or HID bulbs with bare fingers.
• Rotate clockwise to lock it in place, or reinstall the retaining clip if equipped.
• Reconnect the electrical connector firmly.

Step 5: Reinstall the dust cover

• Install the rear dust cover and twist it clockwise until fully seated.
• Make sure the seal is even all the way around.

Step 6: Test both headlights

• Turn the ignition on and switch on the low beams, then the high beams.
• Confirm both sides illuminate evenly.
• If one side does not work, recheck the connector and bulb orientation.
