Compatibility

Directly compatible with Citroën C4 II (B7) rear right outer lamp assemblies that use the listed product codes. Always check the lamp assembly style and connector shape to confirm fitment before installation. Note that the wiring harness may not be included with the socket.

Installation Recommendations

1. Always disconnect the vehicle battery before starting work on the lighting circuit to avoid short circuits and electrical damage.
2. Access the rear lamp from the trunk by removing the trim and unscrewing the lamp assembly fasteners.
3. Remove the lamp assembly, unplug the original socket and extract the old bulb holder from the lamp housing.
4. Compare the new socket with the old one to ensure matching contact pins and locking tabs. Install the new socket into the lamp housing and secure it in place.
5. Reconnect the wiring harness (if provided) or reattach the existing connector. Refit the lamp assembly and fasteners, then reconnect the battery and test all lamp functions (brake, tail, indicator, reverse if applicable).
6. When reassembling, check seals and gaskets for damage to prevent moisture ingress. Use dielectric grease on contacts if available to reduce corrosion risk.

Why The Part Most Often Fails

Bulb sockets commonly fail due to moisture ingress and corrosion of the contact pins, heat damage from overheated or mismatched bulbs, mechanical wear from frequent bulb changes, or deformation of the plastic housing from aging and vibration. Poor electrical contact can cause intermittent lighting, increased resistance and localized heating, which accelerates failure.

Practical Tips

• If contacts show corrosion, clean them carefully or replace the socket to restore reliable connection.
• Use correct rated bulbs to prevent overheating. Avoid touching halogen glass with bare hands.
• Inspect the lamp housing seal and wiring insulation when replacing the socket to prevent repeated failures from water ingress or chafing.

Note

Cabling May Not Be Included In Delivery. Verify that the existing wiring and connector match the replacement socket before final assembly.
