Technical Information

• Manufacturer: Stellantis / Citroën / Peugeot
• Model: Citroën C3 (models up to 2009)
• Product Codes: 6350Q3, 6351Q3, 6350X5, 6351X5
• Additional Numbers: 6350Q3 | 6350X5 | 6351Q3 | 6351X5 | Citroën C3

Function and Application

The part houses the bulb sockets for the rear lamp cluster (left and right) and includes a short length of wiring to connect the lamp module to the vehicle harness. It provides electrical contacts for standard filament bulbs used in tail, brake and indicator circuits. This assembly replaces worn or damaged lampholders and short sections of harness that cause intermittent lighting or open circuits in the rear lights.

How To Replace

• Disconnect Battery Before Work To Prevent Short Circuits.
• Remove Rear Light Assembly: Open boot, remove retaining screws/clips and gently pull the lamp unit out to access the sockets.
• Extract Old Socket: Turn or unclip the old socket from the lamp housing and unplug the connector from the vehicle wiring harness.
• Install New Socket: Fit the new socket into the lamp housing, secure clips or twist into position and connect the wiring tail to the vehicle connector.
• Test Lighting Functions: Reconnect Battery and verify Tail, Brake and Indicator lights operate correctly before reassembling.
• Reassemble Lamp Unit: Reinstall the lamp assembly and tighten fasteners to manufacturer torque where specified.

Installation Recommendations

• Use Dielectric Grease On Contacts To Reduce Corrosion And Improve Long-Term Reliability.
• When Replacing, Inspect Bulbs And Lamp Seals; Replace Any Failed Bulbs And Renew Damaged Seals To Prevent Water Ingress.
• Ensure Connectors Are Clean And Free Of Corrosion; Repair Loom Insulation If Fraying Or Damage Is Present.
• If You Encounter Wiring Damage Beyond The Short Tail, Repair The Wiring Harness With Proper Automotive-Grade Materials.

Why The Part Commonly Fails

Rear lamp sockets fail most often due to moisture ingress and corrosion of the contacts, prolonged heat cycling from filament bulbs, mechanical vibration and brittle plastic after years of service. Water entering the lamp housing accelerates corrosion and can cause intermittent or complete loss of lighting. Damaged wiring insulation or connector pins are also frequent causes of failure.

This replacement socket is a straightforward, cost-effective repair to restore rear lamp functionality on affected Citroën C3 vehicles. Order by the referenced product codes to ensure you receive the correct lampholder assembly for your application.

Function

The socket secures and provides electrical contact for the rear lamp bulbs. Depending on the lamp cluster configuration, it serves tail light, stop light (brake), turn signal (indicator) and/or reverse light functions. Proper seating and contact integrity are essential for reliable illumination and signal transmission.

How To Replace

1. Switch off ignition and all exterior lights before starting. 2. Open the boot and access the rear lamp from inside the luggage compartment—remove cover panels or trim as required. 3. Unscrew or unclip the lamp assembly and pull it out gently. 4. Unplug the wiring connector from the lamp and release the bulb holder/socket from the lamp housing. 5. Replace the old socket with the new one, ensuring bulbs are correctly seated and contacts are clean. 6. Reconnect the wiring connector, refit the lamp assembly and secure all fasteners and trim. 7. Test all lamp functions (tail, brake, indicator, reverse) before finishing reassembly.

Installation Recommendations

Wear gloves to avoid contaminating bulb glass. Inspect wiring plugs and contacts for corrosion or damaged insulation and clean contacts if necessary. Use dielectric grease on connectors to improve moisture resistance. Verify bulb types and orientation before refitting. If multiple lamp functions fail, check the vehicle fuse and ground connections as well.

Why This Part Commonly Fails

Common causes of failure include corrosion from moisture ingress, overheating of bulbs causing melted or brittle plastic, vibration fatigue, and UV degradation over time. Poor contact due to oxidized terminals or damaged wiring can lead to intermittent or complete loss of lamp function. Regular inspection and addressing moisture entry points in the lamp housing help extend service life.

Compatibility And Search Tips

Many customers search by the product codes shown above (6350Q3, 6351Q3, 6350X5, 6351X5) or by the vehicle model Citroën C3. Use these codes when looking for matching parts to ensure correct fitment.

This lamp is compatible with various Citroën and Peugeot models, notably the Citroën C3 from 2005 onwards. It is known to wear out over time due to exposure to harsh weather conditions and vibrations, making timely replacement crucial for maintaining vehicle safety.

Changing the Left Rear Lamp is a simple process that can be accomplished with basic tools. Ensure the vehicle is off before beginning the replacement to guarantee safety. Regular checks are advised as the lamp can diminish in brightness, signalling a need for replacement.
