🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the rear of the headlight housing

• Open the hood and locate the back side of the headlamp assembly.
• If the access area is tight, use the trim panel tool to gently move any plastic retainers or covers blocking access.
• If a nearby air duct or cover is in the way, remove it with the 10mm socket, ratchet, and extension bar.
• Take a photo before removing anything.

Step 2: Remove the old bulb

• Reach behind the headlight and unplug the bulb connector by hand.
• Rotate the bulb socket counterclockwise using your hand, then pull the bulb straight out.
• Do not force it; if it sticks, wiggle gently while turning.

Step 3: Install the new bulb

• Compare the old bulb and new bulb to make sure they match.
• Insert the new bulb into the housing in the same position as the old one.
• Rotate the bulb clockwise by hand until it locks in place.
• Reconnect the electrical connector firmly.
• Keep the bulb glass clean.

Step 4: Repeat on the other side

• Use the same process to replace the bulb on the other headlight.
• Make sure both bulbs are seated fully and both connectors are locked in.

Step 5: Test the headlights

• Turn the ignition on and switch on the headlights.
• Check low beam and high beam operation if your repair included both bulbs.
• Make sure both lights are bright and even.
