Benefits And Application

High-quality body lamp housing engineered to match the original mounting points and connector locations of the Citroën C5 Estate.

How The Part Functions

The upper rear lamp houses the rear lighting elements and their sockets (tail light/brake light/indicator arrangement depends on vehicle equipment). It protects bulbs and wiring from the elements while maintaining the correct light output pattern and visibility required for road safety.

Replacement Procedure

• Open the tailgate and remove the interior trim panel to access the lamp mounting screws and electrical connector.
• Unscrew the securing bolts and carefully pull the lamp assembly outwards to expose the wiring harness.
• Disconnect the electrical connector and remove the lamp. If needed, swap the bulb socket into the new assembly (sockets may be purchased separately).
• Fit the new lamp, connect the wiring, check alignment and sealing, then secure the mounting screws and refit the trim panel.
• Test all lighting functions (tail, brake, indicator, reverse if applicable) before returning the vehicle to service.

Installation Recommendation

Install Using Standard Workshop Tools. Turn Off Ignition And Remove The Key Before Working On Lighting Circuits. Ensure Seals And Fasteners Are Clean To Maintain Waterproofing. Replace Bulb Sockets If Corroded. After Installation, Verify All Functions From Outside The Vehicle And Use A Helper To Operate Brake And Indicator Controls.

Most Common Failure Reasons

• Impact Damage From Minor Collisions Causing Cracked Lenses Or Broken Mounting Tabs.
• Water Ingress Through Damaged Seals Leading To Corrosion Or Short Circuits.
• Burnt Or Intermittent Bulb Contacts Due To Age Or Poor Socket Condition.
• Corroded Or Damaged Connector Pins And Wiring Caused By Moisture Penetration.
