Product Overview

Replacement bulb holder (socket) for the left rear fender tail lamp of Citroën C3 II (A51). This unit includes a short wiring lead for direct connection to the vehicle harness and is commonly found under product codes 6350KQ / 6350.KQ. Ideal for professional workshops and experienced DIY mechanics who need a quick, reliable fix for intermittent or failed rear light circuits.

Function

The socket secures the bulb in the rear lamp assembly and provides the electrical contacts required for brake, tail or indicator functions (depending on the fitted bulb). It also positions the bulb correctly and helps keep electrical contacts stable under vibration.

How It Is Replaced

Replacement typically requires access to the rear lamp assembly from the boot or the wheel-arch side, depending on body style and local trim layout. Remove the relevant trim or inner wing liner to reach the lamp backplate, unplug the old socket from the wiring harness, release any retaining clip or twist-lock holding the socket, remove the faulty socket and insert the new one. Reconnect the wiring lead, refit trims and test all lamp functions (tail, brake, indicator) before finishing. If unsure about access points on a specific vehicle, follow the vehicle manufacturer’s removal procedure.

Installation Recommendations

Always work safely: disconnect the negative battery terminal before starting electrical work to avoid short circuits. Inspect connector pins for corrosion or damage and clean contacts if necessary. Apply a small amount of dielectric grease to contacts to reduce future corrosion. Ensure the socket is fully seated and any retaining clips are engaged. After installation, verify all relevant light functions and check for error messages on vehicles equipped with monitoring systems.

Why This Part Commonly Fails

Common failure causes include corrosion from moisture ingress, brittle or cracked plastic after prolonged heat cycling, broken or fatigued wire leads from vibration, and poor contact due to worn or oxidised pins. These failures typically present as intermittent lighting, flickering, or a complete loss of a lamp function. Regular inspection of rear lamp seals and connectors helps prevent premature failures.
