Installation Recommendations

- Access: Open the boot and remove the inner trim or luggage panel to access the lamp fixing points.
- Removal: Unscrew or unclip the fasteners securing the lamp, carefully pull the assembly out a short distance and disconnect the electrical connector.
- Bulb Transfer: If reusing bulbs or bulb holders, transfer them to the new housing. If sockets are missing, fit the correct holders before installation.
- Reinstallation: Reconnect the electrical connector, check sealing surfaces and gaskets, position the lamp and secure fasteners evenly to avoid distorting the lens.

Most Common Failure Causes
- Impact damage from minor collisions or parking knocks that crack the lens or housing.
- Water ingress or condensation due to degraded seals, leading to corrosion of contacts and sockets.
- Corrosion or poor contact in bulb sockets and connectors causing intermittent function.
- UV and age-related fading or crazing of the plastic lens, reducing light output.
- Failed bulbs or loose connections—often the simplest cause but may require socket replacement if corrosion is present.
