⚠️ Safety & Precautions

• ⚠️ Let the headlights cool first; bulbs get extremely hot.
• ⚠️ Do not touch new bulb glass with bare fingers; skin oil can shorten bulb life.
• ⚠️ If you have factory HID (xenon) lights: turn lights off, remove key, and disconnect the battery negative cable before unplugging the igniter (high voltage).
• ⚠️ Support the hood securely and keep tools away from the battery terminals.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open access to the back of each headlight

• Open the hood and use a flashlight to look behind each headlight housing.
• If the passenger side is tight: loosen/remove the air inlet/airbox fasteners using a 10mm socket, 3/8" ratchet, and 6" extension, then move the intake piece slightly for hand room.
• If the driver side is tight: carefully move any nearby harness clips using a trim clip removal tool (a forked tool that pops plastic clips out without breaking them).

Step 2: Identify your bulb type (Halogen vs HID)

• Halogen usually has a simple bulb connector on the back of the housing.
• HID (xenon) typically has a larger base/igniter module attached to the bulb.
• If you’re unsure, remove the access cover/connector as in Step 3 and compare to the new bulb packaging.

Step 3: Remove the electrical connector

• Press the connector tab and pull straight back by hand. If needed, gently help the tab with a small flathead screwdriver.
• Do not pull on the wires.

Step 4: Remove the old bulb

• Twist the bulb base counterclockwise by hand to unlock it, then pull it straight out.
• Place the old bulb on a shop towel so it doesn’t roll away.

Step 5: Install the new bulb (do not touch the glass)

• Put on nitrile gloves to keep skin oil off the bulb.
• Align the bulb tabs with the housing slots, insert fully, then twist clockwise until it stops.
• If you accidentally touch the glass, wipe it with a clean shop towel before installing.

Step 6: Reconnect the connector and reassemble any removed items

• Push the connector on until it clicks.
• Reinstall any intake/airbox fasteners you loosened using a 10mm socket, 3/8" ratchet, and 6" extension.

Step 7: Repeat on the other headlight

• Do the same steps for the other side so both bulbs match in brightness and color.

✅ After Repair

• If you disconnected the battery, reconnect it using a 10mm socket and 3/8" ratchet and Torque to 5 Nm (44 in-lbs).
• Turn headlights ON and confirm both sides light up.
• Check high beams and low beams (if you replaced both types) and confirm the beam aim looks even against a wall.
• If a bulb doesn’t light: re-check the connector is fully seated and the bulb is fully twisted/locked.
