Rear lamp base Citroën C3 6350Q3, 6351Q3, 6350X5, 6351X5

Description

Socket with bulbs for left and right rear lamp CITROEN C3 up to 2009
Functionality of bulbs not guaranteed

Part description

This rear lamp base is designed for Citroën C3 cars and serves as a carrier for the bulbs and their contacts in the rear light (left and right depending on the design of the lamp). It is suitable for solving problems such as failure of individual lights, intermittent lighting or damaged contacts in the socket.

Light bulbs may be included, however their functionality is not guaranteed – consider them as an accessory. For a reliable result, it is usually worth installing your own certified bulbs.

Installation recommendations

Generally/typically for the rear lamp base, the replacement is simple, but the exact procedure may vary depending on the design of the lamp and the specific side of the car.

1) Before assembly (checks of used part)

• Compare the shape of the socket, the position of the locks and the connector with the old piece.
• Check for burnt contacts, green corrosion or plastic cracks.
• If they are part of the bulb, be aware that their functionality is not guaranteed; it is recommended to measure them or replace them.

2) Necessary tools and materials

• Typical: a basic set of screwdrivers/bits according to the attachment of the covers, a clean cloth
• Contact cleaner (recommended)
• Multimeter or tester (recommended)

3) Step-by-step assembly procedure

1. Turn off the ignition and lights.
2. Provide access to the rear lamp (typically after opening the trunk lid and removing the cover/trim where the lamp is in the way).
3. Disconnect the lead connector from the socket (if separately connected).
4. Release the socket from the lamp (typically by turning or unlocking the locks – depending on the design).
5. Remove the base and check the contact surfaces in the lamp for dirt or damage.
6. Clean the contacts and the connector (with contact cleaner) and let them air out.
7. Replace the bulbs according to their original placement (if you are changing them) to match the positions of the lights.
8. Insert the base into the lamp in the correct position and secure it (snap/turn).
9. Connect the connector and check that it is properly closed and does not hold “half way”.
10. Refit any covers/upholstery.

• 4) Post-assembly checks and test drive/function verification

  • Verify the function of all rear light modes (outline, brake, turn signal, possibly reverse/fog light depending on the equipment).
  • Check that the lights blink when the wiring moves – this could indicate a bad contact.
  • After a short ride, check again that the base is firmly seated and does not move in the lamp.

  5) The most common assembly mistakes + how to avoid them

  • Swapping bulbs/positions – note the placement or use the old socket as a template before disassembly.
  • Socket not seated – make sure the locks are seated; otherwise, transient resistance and light outages occur.
  • Ignoring damaged wiring – if the wires are broken at the connector, the socket alone will not solve the problem.

  Reasons why the part is damaged

  • High transient resistance on the contacts (oxidation, allowed seating) → heating and burning of the socket.
  • Intrusion of moisture into the lamp space → corrosion of contacts and unstable function of the lights.
  • Mechanical damage when disassembling the lamp or carelessly replacing bulbs (cracks, broken locks).
  • Poor quality/unsuitable bulbs or repeated overheating → deformation of plastic and deterioration of contact.
