Why This Part Fails Most Often

Bulb sockets in rear lamps are subject to heat, vibration, moisture, and oxidation, which are the primary causes of failure. Typical failure modes include:

• Corroded Or Pitted Contacts Causing Intermittent Or No Connection.
• Melted Or Deformed Plastic From Overheating (Often Caused By Poor Contact Or High Resistance At The Connector).
• Water Ingress When The Sealing Grommet Is Missing Or Damaged, Leading To Short Circuits Or Corrosion.
• Damaged Wiring From Mechanical Stress Or Rodent Activity.

With normal use, a socket can last many years; failures are more common in vehicles exposed to damp environments, salt, or frequent vibration.

Additional Notes

• Because This Item Does Not Include The Sealing Rubber, Replace The Grommet Or Verify The Lamp Housing Seal To Avoid Moisture Problems.
• Use Clean Bulb Contacts And Correct Bulb Type (P21/5W) To Prevent Overheating And Premature Wear.
• If You Encounter Repeated Contact Failures, Inspect The Wiring And Ground Connections For Corrosion Or Damage.

This rear lamp socket assembly provides the mechanical mounting and electrical connection for the rear light cluster on Citroën C3 vehicles produced up to 2009. The item includes the bulb holder(s) and a short length of wiring for plug-in connection to the vehicle harness. It is intended for both left and right rear lamps depending on the product code. The assembly is designed to accept standard P21/5W dual-contact bulbs used for tail and brake lamp functions.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C3 (up To 2009)
• Product Codes: 6350Q3, 6351Q3, 6350X5, 6351X5
• Other Numbers: Bulb Type P21/5W

Compatibility And Use

Fits Citroën C3 models produced up to 2009. Verify the product code against the part number commonly used in workshop listings: 6350Q3, 6351Q3, 6350X5, 6351X5. The socket carries the electrical contacts for the tail and brake circuits and secures the bulb in the rear lamp housing.

Installation Recommendations

1. Park on a level surface, switch off ignition and, as a precaution, disconnect the negative battery terminal if you expect to handle live wiring.
2. Access the rear lamp from inside the trunk/boot by removing the interior trim panel to expose the lamp cluster fasteners.
3. Unscrew or unclip the lamp cluster, pull the unit out enough to reach the electrical connector and bulb holder.
4. Disconnect the wiring connector, remove the old socket by releasing retaining tabs, and install the replacement holder with matching orientation.
5. Fit the correct P21/5W bulb(s) into the new holder, reconnect the wiring, and test all rear light functions (tail, brake, indicator, reverse if applicable) before reassembly.
6. Reinstall the lamp cluster and interior trim. Inspect seals to ensure the lamp housing is watertight.

Most Common Failure Causes

• Corroded Contacts: Moisture ingress and oxidation of metal contacts cause intermittent or lost electrical connection.
• Connector Heat Damage: Poor contact or overloaded circuits can melt plastic around terminals, deforming the socket.
• Mechanical Wear And Vibration: Repeated removal, impact or vibration can crack the plastic holder or break wiring solder joints.
• Moisture Ingress: Damaged seals on the lamp housing allow water to reach the socket and bulbs, accelerating failure.
• Bulb Failure: Individual bulbs may be non‑functional — the supplied bulbs’ functionality is not guaranteed.

For longer service life, ensure the lamp housing seal is intact, use dielectric grease on contacts to slow corrosion, and avoid excessive bulb wattage. When replacing the socket, check the vehicle wiring for signs of overheating or damage and repair as needed before final assembly.
