Description
Tail light socket assembly for the rear lower lamp of Citroën C5 I and II Estate. Functionality of the bulbs is not guaranteed.
This rear lower lamp socket assembly is intended as a direct replacement for the Tail Light unit on Citroën C5 I and C5 II estate models. It supplies the electrical contacts and lamp holders for the rear lower lamp cluster, restoring reliable connections for tail, brake and indicator circuits where wiring or sockets have failed. Frequently searched by part number 6534JZ, the unit is aimed at professional mechanics and experienced DIYers who require a fast, correct-fit solution during bodywork or lighting repairs.
Designed to be fitted in the original mounting points, the assembly reduces repair time compared with rewiring individual sockets. Use this harness when sockets are corroded, wiring insulation is damaged, or after minor rear impacts that deform the lamp holder. Installation is straightforward for a workshop with basic hand tools, and replacement typically returns the lamp functions to reliable operation provided the bulbs and connectors are in good condition.
Technical Information

- Model: Citroën C5 I, Citroën C5 II — Estate (Station Wagon)
- Product Codes: 6534JZ
- Additional Numbers: NFP
Installation Recommendations
- Prepare Tools: Philips/torx drivers, trim removal tools, pliers, electrical contact cleaner, dielectric grease.
- Access: Open the tailgate and remove interior trim or trim screws to reach the rear lower lamp cluster. In some cases the bumper or inner wheel arch liner must be loosened for clearance.
- Removal: Unscrew and release the lamp cluster, gently pull it out and unplug the old bulb holders and connectors. Note routing and clip positions to fit the new assembly identically.
- Fitment: Install the new socket assembly into the lamp cluster, secure all clips and fasteners, and reconnect the electrical plugs. Apply a small amount of dielectric grease to contacts to help prevent future corrosion.
- Check: Test all lamp functions (tail, stop, indicator, reverse if applicable) before reassembling trim. Ensure rubber grommets and seals are intact to prevent water ingress.
Why This Part Commonly Fails
- Moisture Ingress: Seals and grommets degrade over time, allowing water to reach contacts and cause corrosion or short circuits.
- Corroded Contacts: Oxidation of bulb sockets and connector pins leads to poor contact, intermittent lighting or complete failure.
- Mechanical Damage: Minor collisions, improper removal or brittle plastic clips can break the holder or wiring mounts.
- Aging Insulation: Heat and UV exposure make wiring insulation brittle, increasing risk of chafing and open circuits.
If the rear lamp shows intermittent operation, dim lighting or an open circuit in one of the lower lamp functions, replacing the socket assembly is a common and effective repair. Search by part number 6534JZ for quick identification. For best results replace worn bulbs and ensure all seals are correctly seated during reassembly.
