This replacement tail lamp bulb socket is designed for technicians and DIY motorists who maintain Citroën C1 and Peugeot 107 vehicles. The part restores a reliable electrical connection in the rear light cluster, eliminating flicker, intermittent contact and poor grounding caused by worn or damaged sockets. Frequently searched by OE and reference numbers, this item is suitable when the original holder has cracked, corroded or melted around the terminals.

Technical Information

• Manufacturer: Stellantis / Citroën / Peugeot
• Model: Citroën C1 (First Series), Peugeot 107 (First Series)
• Product Codes: 81560-0H060, 6350X8, 6350X6
• Other Numbers: 634686

Fitment

Compatible With: Citroën C1 First Generation (2005–2014), Peugeot 107 First Generation (2005–2014). Intended For Use In Rear Light Assemblies As The Bulb Socket/Holder.

Installation Recommendations

• Prepare: Park on a level surface, switch off ignition and remove the negative terminal of the battery for added electrical safety.
• Access: Open the boot and remove the interior trim or access panel behind the tail light cluster. Unscrew or unclip the tail lamp to reach the socket.
• Remove Old Socket: Twist or unclip the old holder from the lamp housing, disconnect the wiring plug and carefully extract any retained bulb(s). Inspect wiring for heat or corrosion damage.
• Install New Socket: Insert the new holder into the lamp housing until it locks, reconnect the wiring plug and install correct bulbs. Use a dielectric grease sparingly on contacts to reduce future corrosion.
• Test: Reconnect the battery, test all rear light functions (tail, brake, indicator, reverse if applicable) before reassembling trim and securing the lamp.
• Tip: Replace compromised bulbs and clean contact surfaces to ensure long-term reliability. Avoid using higher-wattage bulbs than specified, as they accelerate socket deterioration.

Most Common Failure Causes

Bulb holders in rear lamps typically fail due to moisture ingress and corrosion, heat damage from over-wattage bulbs or poor ventilation, mechanical fatigue and cracking of the plastic after years of vibration, and loosening or burning of electrical contacts that create intermittent connection or total failure. Road salt and contaminated water accelerate corrosion, especially in vehicles used in cold climates or with frequent short trips.

Note: This listing refers to the bulb holder only. The functionality of bulbs themselves is not guaranteed and should be checked separately. Many customers search using OE numbers like 81560-0H060, 6350X8, 6350X6 or reference 634686 to find the correct replacement quickly.

This replacement bulb socket with wiring harness is designed for rear light applications on first‑generation Citroën C1 and Peugeot 107 vehicles. It provides a direct-fit electrical connection for standard rear bulbs and is commonly sought by mechanics and DIY enthusiasts under part numbers such as 634686, 6350X8 or 81560-0H060. The included pigtail cable simplifies installation when the original wiring or connector is damaged.

The part is ideal for quick repairs to restore a secure bulb connection and prevent intermittent lighting faults. Note that this listing covers the socket and short cable only; bulbs are not guaranteed to be functional and are usually replaced separately.

Function And Fitment

The socket secures rear lamp bulbs in the tail light assembly and provides the electrical contact for stop, tail or indicator bulbs depending on the lamp position. The short cable section allows reconnection to the vehicle wiring loom when the original connector is cracked, corroded or the wiring is cut. This part fits the rear lamp assemblies used on first‑generation Citroën C1 and Peugeot 107 models.

Recommended Installation

1. Park on a level surface, switch off the ignition and remove the key. For safety, disconnect the negative battery terminal if you will be handling wiring extensively.
2. Open the boot and remove the trim or access panel to reach the tail light cluster. On C1/107 models this is usually accessible from inside the boot after removing a few fasteners.
3. Unscrew or unclip the tail light unit and gently pull it clear. Unplug the main connector and remove the bulb holder by pressing the locking tab and turning or pulling as required.
4. Release the old socket from the lamp, fit the replacement socket into the bulb holder, and connect the supplied cable to the vehicle loom (secure with the original connector or suitable crimp/heat‑shrink joints).
5. Test the lamp functions (tail, brake, indicator) before refitting the lamp and trim. Ensure all connections are tight and protected from moisture.

Why This Part Commonly Fails

• Corrosion: Water ingress or condensation in the tail lamp can corrode contacts and cause intermittent or failed connections.
• Heat And Vibration: Repeated heating cycles from bulbs and road vibration can crack plastic sockets and weaken contacts over time.
• Mechanical Damage: Impact, over‑tightening when refitting the lamp, or incorrect bulb removal can break the socket or wiring.
• Ageing Wiring: Insulation becomes brittle on older cars, leading to exposed wires or broken pigtails.

For a durable repair, clean the lamp housing, replace any damaged seals to prevent future moisture ingress, and use proper electrical connectors when joining wires. Regular inspection of rear lamps during service intervals helps catch socket degradation early and avoids driving with a non‑working rear light.
