⚠️ Safety & Precautions

• Turn the lights off and remove the key before starting.
• Let the bulbs cool fully before touching them; they get very hot.
• Do not touch the glass part of a halogen bulb with bare fingers. Oil from skin can shorten bulb life.
• If your replacement bulbs are HID or LED conversions, the procedure changes. This guide assumes factory-style halogen bulbs.
• No battery disconnect is required for this repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and access the back of the headlight

• Open the hood and locate the rear side of each headlight housing.
• On some cars, you may need to move a few plastic retainers or remove a small cover for better access. Use the trim clip removal tool if needed.
• Work one side at a time.

Step 2: Remove the rear bulb cover

• Twist the rear dust cover counterclockwise by hand and remove it from the headlight housing.
• If it is tight, use a clean glove-covered hand for better grip.
• Set the cover aside where it stays clean.

Step 3: Disconnect the bulb connector

• Press the release tab on the bulb connector and pull it straight off the bulb.
• Do not pull on the wires. Pull on the connector body only.
• A little wiggle helps if it is stuck.

Step 4: Remove the old bulb

• Rotate the bulb counterclockwise to unlock it, then pull it straight out.
• Keep the bulb upright so you can compare the tab shape and seating position with the new one.
• Inspect the socket area for dirt or moisture.

Step 5: Install the new bulb

• Put on nitrile gloves before handling the new bulb.
• Align the bulb tabs with the slots in the headlight housing and insert it straight in.
• Rotate the bulb clockwise until it locks in place.
• Reconnect the electrical connector until it clicks.
• Do not force the bulb.

Step 6: Reinstall the dust cover

• Inspect the dust cover seal for damage or dirt.
• Install the cover and twist it clockwise until fully seated.
• Make sure the cover is sealed tightly to keep moisture out.

Step 7: Repeat on the other side

• Repeat the same steps for the other headlight bulb.
• Replace bulbs in pairs so light output stays even.

✅ After Repair
