Fitment / Compatibility
Intended for Citroën C4 Picasso models requiring the OE reference numbers listed above. When searching for replacements, technicians often use the product codes 9653547480 or 6351CA to locate the correct socket. Verify physical match with the existing lamp assembly before installation.
Installation Instructions
Basic replacement steps for a trained technician or an experienced DIYer:
- Disconnect the vehicle battery before starting work when handling electrical connectors to avoid short circuits.
- Access the rear lamp: remove inner trim or wheelarch liner as required to reach the lamp housing.
- Remove the lamp assembly or access cover, unplug the old socket from the bulb and wiring harness.
- Cut back any damaged wiring if necessary and prepare wires for connection (solder/crimp recommended).
- Fit the new socket into the lamp, reconnect the wiring stub to the vehicle harness using proper connectors and insulation.
- Test all lamp functions (tail, brake, indicator) before reassembling trim and securing the lamp.
Recommended Installation Tips
- Use proper crimp connectors or solder joints with heat-shrink tubing for a reliable, vibration-resistant connection.
- Apply dielectric grease to the metal contacts to reduce corrosion and improve conductivity.
- Check bulbs for correct type and seating; replace any brittle or discolored bulbs at the same time.
- Ensure wiring is routed clear of moving parts and secured to prevent chafing.
Why The Part Fails
- Corrosion From Moisture: Water ingress through a damaged lamp seal causes oxidation of contact pins and poor electrical connection.
- Heat And Cycling: Repeated heating from bulbs causes plastic deformation or contact wear over time.
- Vibration And Mechanical Damage: Road vibration or impact can break pins, deform the socket or damage wiring.
- Poor Connections During Bulb Changes: Bent or pushed-back contacts when replacing bulbs lead to intermittent or failed circuits.
Final Notes
This socket is a practical repair item to restore lamp function without replacing the entire lamp cluster. For a durable repair, address the root cause such as damaged lamp seals or wiring corrosion at the same time. The listed product codes (9653547480, 6351CA) are useful search terms for finding the correct replacement in parts catalogs and workshop databases.
