Warnings

Tools required

Parts

• Tail light bulb (verify specific bulb type for brake/turn/reverse) × 1 — Use OEM specification or check owner's manual for bulb type

Preparation

1. Park vehicle on level surface and turn off ignition
2. Open trunk fully and ensure adequate lighting
3. Identify which bulb needs replacement (brake, turn signal, reverse, or tail light)
4. Purchase correct replacement bulb before starting work

Procedure

1. 1

   Access trunk liner
   Open the trunk and locate the fabric or carpet trunk liner on the side where the tail light needs service. Identify the access panel or fasteners securing the liner behind the tail light assembly.
2. 2

   Remove trunk liner panel
   Pull back or remove the trunk liner access panel to expose the rear of the tail light assembly. Some models use plastic clips or Velcro; gently peel back the liner to reveal the bulb sockets on the back of the tail light housing.
3. 3

   Identify bulb socket
   Locate the specific bulb socket that corresponds to the failed bulb. The assembly typically has multiple sockets for brake light, turn signal, reverse light, and tail light. Each socket is usually labeled or color-coded.
4. 4

   Remove bulb socket
   Grasp the bulb socket firmly and rotate counterclockwise approximately 1/4 turn until it releases from the tail light housing. Pull the socket straight out from the housing with the bulb still attached.
5. 5

   Remove failed bulb
   Depending on bulb type, either pull the bulb straight out of the socket (wedge-type) or push in slightly and rotate counterclockwise to release (bayonet-type). Handle the old bulb carefully as it may be hot or broken.
6. 6

   Install new bulb
   Insert the new bulb into the socket. For wedge-type bulbs, push straight in until seated. For bayonet-type, align the pins, push in, and rotate clockwise until locked. Avoid touching the glass portion of halogen bulbs with bare fingers.
7. 7

   Reinstall bulb socket
   Insert the bulb socket back into the tail light housing, aligning the tabs. Rotate clockwise approximately 1/4 turn until the socket locks securely into place. Ensure the socket is fully seated and cannot be pulled out.
8. 8

   Test bulb operation
   Before closing everything up, turn the ignition to ON position and test the new bulb. Have an assistant press the brake pedal, activate turn signals, or shift to reverse depending on which bulb was replaced. Verify proper illumination.
9. 9

   Replace trunk liner
   Reinstall the trunk liner panel or fold the carpet liner back into its original position. Ensure all clips or fasteners are properly secured and the liner sits flush without interfering with the tail light assembly.

Reassembly

1. Ensure trunk liner is properly secured and does not rattle
2. Verify no tools or parts are left in the trunk compartment
3. Close trunk and verify tail light assembly is properly seated from exterior

Verification

• Test all tail light functions with ignition on: brake lights with brake pedal pressed, turn signals with switch activated, reverse lights in reverse gear, and running lights with headlights on
• Perform walk-around inspection to confirm proper operation and no condensation or gaps in tail light assembly
• Verify bulb remains illuminated and does not flicker during operation
