Right rear lamp bolt base with Citroën C1 Peugeot 107 634681 cable cable

Description

Right rear lamp bulb socket with wiring piece for CITROEN C1 and PEUGEOT 107
The functionality of the bulbs themselves is not guaranteed

Part description

This right rear lamp bulb socket with attached piece of wiring is intended as a replacement part for the repair of the rear lighting. It is useful for defects such as light outages, flickering, overheating of contacts or a damaged connector/cable at the lamp. Thanks to the added length of cable, it is often easier to make a quality connection to the original harness.

Warning: the functionality of the bulbs themselves is not guaranteed – treat the part primarily as a socket and wiring.

Installation recommendations

Generally/typically for tail lamp bulb socket with wiring: exact procedure may vary depending on lamp design and connectors.

1) Before assembly

• Compare the new part with the old one: the shape of the socket, the location of the contacts, the method of arresting, the length and termination of the cable.
• Check the contacts in the socket: they must not be burnt, loose or significantly oxidized.
• Inspect the wiring: look for hardened insulation, cracks, “greening” of copper, or previous poor connections.
• If you also throw light bulbs around, be aware that their functionality is not guaranteed.

2) Necessary tools and materials (in general)

• Basic set of screwdrivers/bits, or small pliers
• Multimeter or tester (recommended)
• Material for high-quality connection of wires: crimp connectors or soldering, shrink tube, insulating tape
• Electrical contact cleaner (recommended)

3) Step-by-step assembly procedure

1. Turn off the ignition and lights.
2. Disconnect the battery (recommended for wiring work).
3. Get access to the tail lamp (typically through the boot liner or service cover).
4. Disconnect the lamp connector and remove the old socket from the lamp body (it is usually secured with a twist or latches).
5. Check the inside of the lamp and the seating surface of the base – clean dirt and possible oxidation.
6. If you will connect the cable: prepare the original wires (healthy section, no corrosion), strip them and check the colors/positions.
7. Connect the wires (crimp or solder) and carefully insulate each connection (ideally with a shrink tube).
8. Arrange the cable so that it does not stretch, break on edges, or get pinched by trim.
9. Place the socket back into the lamp and lock it properly.
10. Connect the connector and check that the connector locks hold and the contact is not loose.
11. Connect the battery.

• 4) Post-assembly checks and functional test verification

  • Test all rear light functions (outline, brake, turn signal, reverse, fog light – depending on equipment).
  • Check that the lights do not flicker when you tap the lamp or move the wiring.
  • After a short ride, check that the connector/socket does not get excessively hot (a sign of poor contact).

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

  • Swapping wires when wiring – always compare positions and verify functions, ideally with a multimeter.
  • Poorly insulated connections – leads to oxidation and blackouts; use heat shrink tubing and solid connections.
  • Non-seated socket in the lamp – will cause poor contact or leakage; check for locking and proper seating.
  • Leaving oxidation on contacts – clean and use contact cleaner for a stable connection.

  Reasons why the part is damaged

  • Burnt or loose contacts due to long-term transient resistance (weak contact = heat).
  • Moisture in the rear lamp and subsequent corrosion of contacts and wires.
  • Damage to wiring due to friction, pinching or pulling during disassembly and repair.
  • Poor quality previous repairs (twisted joints, poor insulation) that lead to oxidation and light outages.
