Description
Socket with bulbs for the rear lamp (left and right), with a piece of wiring
For CITROEN C3 up to 2009
Bulb functionality not guaranteed
Product Description
This rear lamp bulb holder with a short section of wiring is intended for Citroën C3 models produced up to 2009. The part provides the connection between the vehicle wiring loom and the rear light bulbs, serving both left and right lamp assemblies. Ideal for mechanics and experienced DIY enthusiasts who need a direct replacement part identified by product codes 6350Q3, 6351Q3, 6350X5 and 6351X5.
Application And Function
The bulb socket secures and contacts the rear light bulbs for functions such as tail lights, brake lights and turn signals depending on the lamp assembly design. It transfers power from the vehicle harness to the bulb filaments and keeps the bulb positioned in the lamp housing. A reliable contact and intact wiring are essential for correct lighting function and vehicle safety.
Replacement Procedure
- Ensure vehicle is parked safely and ignition is off. For safety, disconnect the negative battery terminal before working on the lamps.
- Remove the tail light assembly according to the vehicle repair manual (access via trunk or inner wheel arch depending on model year).
- Extract the old bulb holder from the lamp housing by turning or unclipping it, then disconnect the wiring connector or cut old wiring if required.
- Fit the new socket into the lamp housing, route the wiring so it is not under tension and reconnect to the vehicle harness. If wiring was cut, make secure soldered joints or high-quality crimp connections and insulate with heat-shrink tubing.
- Fit bulbs (note: bulb functionality not guaranteed by this part) and test all lamp functions before final assembly.
- Refit the lamp assembly and reconnect the battery. Verify operation of tail, brake and indicator lights on both sides.
Installation Recommendations
- Use dielectric grease on electrical contacts to reduce corrosion and improve longevity.
- Replace corroded bulb bases and damaged wiring rather than attempting temporary repairs.
- Secure wiring with clips or cable ties to prevent chafing and mechanical strain.
- Check lamp gaskets and seals to avoid water ingress which accelerates socket failure.
- If soldering is required, use proper insulation (heat-shrink) and protect the splice from moisture.
Most Common Failure Reasons
Rear lamp sockets and associated wiring most commonly fail due to moisture ingress and corrosion of contacts, thermal stress from repeated heating/cooling cycles, mechanical damage from impacts or improper handling, and brittle plastic after long-term exposure to heat and UV. Poor ground connections or intermittent contact can also cause flashing or non-functioning bulbs.

Notes For Professionals
This part is suitable for workshop installation. When replacing rear lamp sockets, verify connector seating and insulation integrity. Testing the lighting circuit with a multimeter or test lamp after installation will confirm proper operation before road use.
