Parts

• H11 halogen headlight bulb (low beam) or 9005 (high beam) × 1 — Use OEM specification - verify bulb type before purchase

Preparation

1. Turn off headlights and ignition, remove key from vehicle
2. Allow headlight assembly to cool if vehicle was recently operated
3. Open hood and secure with prop rod
4. Identify which bulb needs replacement (low beam or high beam) from front of vehicle
5. Put on clean, lint-free work gloves to handle new bulb

Procedure

1. 1

   Locate bulb access cover
   From the engine bay, locate the circular plastic access cover on the back of the headlight assembly. The low beam bulb is typically positioned on the outboard side, while the high beam is more toward the center of the vehicle. The cover will be approximately 4-5 inches in diameter.
2. 2

   Remove bulb access cover
   Rotate the access cover counterclockwise approximately 1/4 turn until it releases. Pull the cover straight back and away from the headlight assembly. Set the cover aside in a clean location.
3. 3

   Disconnect electrical connector
   Locate the electrical connector attached to the base of the bulb. Press the release tab on the connector and pull it straight off the bulb base. You may need to wiggle it gently while pulling. Do not pull on the wiring harness itself.
4. 4

   Remove bulb retaining clip
   Identify the wire retaining clip that holds the bulb in place. Press the wire clip toward the bulb and unhook it from the retaining bracket. Swing the clip out of the way to allow bulb removal. The clip will remain attached to the housing.
5. 5

   Extract old bulb
   Carefully pull the old bulb straight out of the socket. Avoid twisting or rocking the bulb excessively. Inspect the bulb socket for any corrosion, moisture, or damage. If moisture is present, dry thoroughly before installing new bulb.
6. 6

   Install new bulb
   Remove the new bulb from its packaging using clean gloves. Handle only by the plastic base, never touching the glass. Insert the new bulb straight into the socket, ensuring the tabs on the bulb base align with the slots in the housing. Push firmly until the bulb is fully seated.
7. 7

   Secure retaining clip
   Swing the wire retaining clip back over the bulb base. Hook the clip into the retaining bracket and ensure it clicks into place, firmly securing the bulb. Verify the bulb cannot be pulled out with gentle hand pressure.
8. 8

   Reconnect electrical connector
   Push the electrical connector straight onto the bulb base until you hear or feel a click. Gently tug on the connector to verify it is fully seated and locked in place.
9. 9

   Reinstall access cover
   Position the access cover over the opening in the headlight assembly. Align the tabs and rotate clockwise approximately 1/4 turn until it locks into place. Ensure the cover is fully seated against the housing.

Reassembly

1. Verify access cover is properly seated and secured
2. Close hood completely

Verification

• Start the vehicle and turn on the headlights to verify the new bulb illuminates properly
• Test both low beam and high beam functions to confirm correct operation
• Turn off headlights, exit vehicle, and visually inspect from the front to verify proper light output and beam pattern
• Check that no warning lights are illuminated on the instrument cluster
