Description
Rear bulb holder for right and left tail lights for Citroën C2 with a piece of wiring.
Product Description
High-quality rear bulb holder designed for both right and left tail light assemblies of the Citroën C2. This replacement socket arrives with a short piece of wiring ready for direct mounting or splicing into the existing harness. It is an ideal part for workshops and DIY mechanics who need a reliable electrical connection for brake, tail and indicator bulbs.
Key Benefits
- Direct fit for Citroën C2 tail light clusters (right and left).
- Includes wiring stub to simplify installation and ensure secure contact.
- Restores reliable electrical contact, reduces flicker and intermittent lighting faults.
- Compact design compatible with standard vehicle bulb types used on C2 models.
How It Works And Typical Faults
The bulb holder secures the bulb and provides the electrical connection between the vehicle wiring and the lamp filament. Common failure modes include terminal corrosion, heat-related deformation of the plastic socket, cracked contacts from mechanical stress and damage to the wiring or connector insulation. Moisture ingress and repeated thermal cycling accelerate deterioration, which leads to poor contact, flickering lights or a complete loss of function.
Replacement Procedure
Recommended for experienced DIYers and professional technicians. Typical replacement steps:
- Disconnect the vehicle battery before starting work to avoid short circuits.
- Access the tail light assembly by opening the boot and removing the fasteners or trim to reach the lamp cluster.
- Remove the lamp cluster from the body and unplug the original bulb holder connector.
- Extract the old socket from the cluster, noting the bulb orientation and wire routing.
- Fit the new bulb holder into the lamp, connect the wiring stub by soldering or using suitable automotive crimp connectors and insulate the joints with heat-shrink or quality tape.
- Refit the lamp assembly, reconnect the battery and test all light functions (tail, brake, indicator) before final assembly.
Mounting Recommendations
Use dielectric grease on terminals to reduce corrosion risk and improve long-term contact. Secure any spliced wiring away from sharp edges and moving parts to prevent chafing. If multiple contacts are corroded, inspect the whole harness section and replace or repair damaged wires rather than relying on repeated socket changes.
Why This Part Fails Most Often
Failures are usually caused by moisture penetration and corrosion of metal contacts, heat-related aging of the plastic socket, and mechanical damage during bulb changes or removal/installation of the lamp cluster. Poor crimping or electrically weak splices in the original repair can also lead to intermittent faults.

Notes For Professionals
This part is commonly used in repair workshops when restoring tail light function. Check bulb type compatibility and connector polarity before final installation. When replacing the socket as part of an electrical repair, always verify wiring integrity upstream to prevent repeat failures.
