Tools required

Parts

• H13/9008 headlight bulb × 1 — Use OEM specification or quality aftermarket equivalent

Preparation

1. Ensure headlights have been off for at least 10 minutes to cool
2. Open and secure hood in upright position
3. Identify which headlight bulb requires replacement (driver or passenger side)
4. Verify replacement bulb is correct H13/9008 type for low/high beam application

Procedure

1. 1

   Remove headlight bezel retaining screws
   Locate the four Torx T15 screws securing the chrome headlight bezel ring around the headlight lens. Remove all four screws and carefully pull the bezel away from the fender, being careful not to scratch the paint. Set bezel and screws aside in a safe location.
2. 2

   Remove headlight housing retaining ring
   With the bezel removed, locate the black plastic retaining ring that secures the headlight housing to the mounting bucket. Rotate the retaining ring counterclockwise approximately 1/4 turn until it releases from its bayonet-style lock tabs. Pull the ring forward and set aside.
3. 3

   Pull headlight housing forward
   Carefully pull the entire headlight housing straight forward out of the mounting bucket approximately 4-6 inches to access the rear of the housing. Do not pull too far or disconnect any wiring yet. Support the housing with one hand to prevent strain on the wiring harness.
4. 4

   Disconnect bulb electrical connector
   Locate the H13 bulb electrical connector at the rear of the headlight housing. Press down on the release tab while pulling the connector straight back away from the bulb socket to disconnect it. The connector should separate with moderate force.
5. 5

   Remove bulb retaining collar
   Locate the wire spring retaining collar that holds the bulb in the reflector housing. Press the collar tab inward toward the center and rotate it counterclockwise to unhook it from the housing. Swing the collar out of the way to release the bulb.
6. 6

   Remove failed bulb
   Carefully pull the old H13 bulb straight out of the headlight reflector housing. Inspect the bulb base and socket for any signs of corrosion, melting, or damage. If damage is present, the entire headlight housing may require replacement.
7. 7

   Install new bulb
   Put on nitrile gloves or use a clean cloth to handle the new bulb. Without touching the glass envelope, align the bulb tabs with the slots in the reflector housing and insert the bulb straight in until it seats fully against the housing. Ensure the bulb is fully seated and oriented correctly.
8. 8

   Secure bulb retaining collar
   Swing the wire spring retaining collar back over the bulb base and rotate it clockwise while pressing outward until it locks into the housing tabs. Verify the collar is fully engaged and the bulb cannot move.
9. 9

   Reconnect electrical connector
   Push the H13 electrical connector straight onto the bulb terminals until it clicks and locks into place. Gently tug on the connector to verify it is fully seated and secured.
10. 10

    Test bulb operation
    Before reinstalling the housing, turn the ignition to the ON position and test both low and high beam operation to confirm the new bulb functions correctly. Turn off lights before proceeding.
11. 11

    Reinstall headlight housing
    Carefully push the headlight housing straight back into the mounting bucket, ensuring the housing seats fully and sits flush with the fender. Align the tabs on the housing with the slots in the bucket.
12. 12

    Install retaining ring and bezel
    Place the black plastic retaining ring over the headlight housing and rotate clockwise approximately 1/4 turn until it locks into the bayonet tabs. Position the chrome bezel over the headlight and install the four Torx T15 screws, tightening them evenly in a cross pattern to avoid distorting the bezel.

Reassembly

1. Ensure all four bezel screws are snug but do not overtighten as this may crack the plastic housing
2. Verify the headlight housing sits flush with no gaps between the bezel and fender
3. Clean headlight lens with glass cleaner if fingerprints or dirt are present

Verification

• Turn ignition to ON position and verify low beam operates correctly
• Test high beam operation and verify proper function
• Check that headlight beam pattern is centered and at proper height; adjust if necessary using adjustment screws on rear of housing
• Verify no warning lights appear on instrument cluster
• Visually inspect that bezel is properly seated with even gaps around entire perimeter
