• Let bulbs cool for at least 10 minutes; they get extremely hot.
• Wear gloves; skin oil on the bulb glass can shorten bulb life.
• Do not touch the new bulb’s glass. If you do, clean it with isopropyl alcohol and a lint-free cloth.
• No battery disconnect is required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify which front-end style you have

• Look at how the headlamp assembly is retained from the top.
• If you see two long vertical metal pins you can pull up by hand, use the “Pin-retained headlamp” steps below.
• If you see two vertical metal retainers/clips near the radiator support that slide/pull up, use the “Clip-retained headlamp” steps below.

Step 2: Pin-retained headlamp (common on “Classic” style front end) — remove the headlamp assembly

• Use your fingers (or a trim clip tool if tight) to pull the two vertical retaining pins straight up.
• Set the pins aside where they won’t fall into the engine bay.
• Use both hands to pull the headlamp assembly straight forward to release it.

Step 3: Clip-retained headlamp (common on “New Body Style” front end) — remove the headlamp assembly

• Use a small flathead screwdriver to gently lift the locking tab (if present), then pull the two vertical retainers straight up.
• Use both hands to pull the headlamp assembly straight forward to release it.

Step 4: Remove the old bulb

• Reach behind the headlamp assembly and locate the bulb socket you’re replacing.
• Twist the bulb socket counterclockwise (by hand) to unlock it, then pull it straight out.
• Press the connector lock and unplug the wiring connector from the bulb.
• Tip: Take a photo so orientation is easy.

Step 5: Install the new bulb

• Put on nitrile gloves before handling the new bulb.
• Plug the wiring connector onto the new bulb until it clicks.
• Insert the bulb into the headlamp housing in the same orientation as the old one.
• Twist the bulb socket clockwise until it locks fully.

Step 6: Reinstall the headlamp assembly

• Slide the headlamp assembly back into place, lining up the guide pins/locators.
• Reinstall the retainers:
• For pins: push the two vertical retaining pins fully down by hand.
• For clips/retainers: slide the two vertical retainers fully down until seated.

Step 7: Repeat on the other side

• Use the same steps to replace the bulb on the other headlamp assembly.
• Use a flashlight to confirm connectors are fully seated.

✅ After Repair

• Turn the headlights on and verify the replaced bulbs work (low beams and/or high beams).
• Check that both headlamps look even in brightness and color.
• At night, confirm the beam aim looks normal; if one looks “off,” the bulb may not be fully locked in.
