Socket With Bulb For Both Right And Left Rear Inner Lamp
For CITROËN C5 II Sedan
With A Piece Of Wiring
Bulb Functionality Not Guaranteed
Overview
This replacement rear lamp socket (bulb holder) is designed for the inner rear light cluster of the Citroën C5 II sedan. The unit includes a short length of wiring harness to simplify installation. It is a practical part for workshops and competent DIYers who search by part number (89032717, 6350V4, 6351V4) when sourcing an immediate, vehicle-specific repair.
Function
The socket secures the bulb in the inner rear lamp, provides the electrical contacts for tail, stop or indicator bulbs, and routes the connection into the vehicle wiring. A reliable socket ensures good electrical contact and stable lighting operation; a damaged socket can cause intermittent lights, poor contact or open circuits.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C5 II (Sedan)
- Product Codes: 89032717
- Additional Numbers: 6350V4, 6351V4
Fitment And Compatibility
Primarily for Citroën C5 II sedan rear inner lamp assemblies. The part is commonly identified and ordered by the product codes listed above, so customers searching by those numbers will find this exact item. Compatibility is typically with vehicles fitted with the corresponding inner tail light housings used on C5 II models.
Replacement Procedure
- Open the trunk and remove the trim panel to access the inner side of the tail lamp.
- Unscrew or unclip the tail lamp assembly retaining bolts and gently pull the lamp out to expose the bulb sockets.
- Disconnect the original socket from the lamp cluster — press any retaining tabs and rotate if fitted as a bayonet type.
- Cut or unplug the vehicle connector if the original socket is damaged; fit the supplied wiring piece and ensure secure crimps or solder joints with heatshrink for insulation.
- Insert the new socket into the lamp, reinstall the lamp assembly and trim panels, then test all lamp functions (tail, stop, indicator) with the vehicle electrics powered.
Installation Recommendations
- Disconnect The Battery Or Isolate The Circuit Before Working On Vehicle Wiring To Prevent Short Circuits.
- Use Proper Electrical Connectors: Crimp Terminals Or Solder With Heatshrink For A Durable Repair.
- Inspect Lamp Sockets And Wiring For Corrosion Or Heat Damage When Replacing; Replace Any Compromised Wiring Sections.
- Ensure Bulb Types Are Correctly Rated And Properly Seated; Note That Bulb Functionality Is Not Guaranteed With This Unit.
- After Installation, Verify All Lighting Functions From Outside The Vehicle And With Diagnostic Tools If Available.
Why This Part Most Often Fails
Sockets in rear lamp clusters commonly fail because of moisture ingress and corrosion of the metal contacts, thermal cycling from repeated bulb heating, vibration that loosens contacts, and plastic aging or cracking from UV exposure. Poor or overheated bulbs and loose connections accelerate deterioration. Replacing the socket and addressing any wiring corrosion usually restores reliable function.
Notes For Workshops And DIYers
Part numbers 89032717, 6350V4 and 6351V4 are commonly used in search queries; listing these in your order or search will help locate the correct item quickly. The supplied short wiring piece is useful for straightforward repairs but always check the condition of the surrounding wiring loom and lamp seals to prevent repeat failures.
