Installation Recommendations
Installation is straightforward for a trained mechanic or an experienced DIYer. Typical steps:
- Access the rear lamp area from the luggage compartment by removing the trim or cover.
- Unscrew the retaining bolts/clips securing the fog lamp housing and carefully pull the unit out.
- Disconnect the electrical connector and remove the old assembly (or socket) from the vehicle.
- Fit the replacement unit, connect the socket, and secure the housing. Ensure gaskets and seals sit correctly to prevent water ingress.
- Test the fog lamp function before reassembling interior trim. Check polarity and connector condition if the lamp does not illuminate.
Use basic hand tools, wear gloves to protect the lens, and inspect the connector for corrosion. If seals are damaged, replace them or apply suitable sealant to maintain watertight integrity.

Replace the assembly if the lens is cracked, mounting points are damaged, or if electrical faults persist after checking connectors and fuses. Because the part is often searched by OE number, use the listed product codes to speed up identification and ensure you order the correct unit.
Suitable for professional workshops and competent DIYers who perform exterior light replacements. The item is supplied complete with socket for quick swap; verify bulb condition after installation and replace the bulb if required.
