The part is tested, all LEDs are fully functional
Center high-mounted stop lamp
This high-mounted third brake light is a direct-fit replacement designed for Citroën C5 I and C5 II Estate (Tourer/Combi) models. Supplied under code 6350P6, it restores the visibility of your vehicle’s brake signal and improves safety for driving and towing. The LED assembly is compact, weather-sealed and intended for mechanics and DIY enthusiasts who need a reliable, OEM-style solution.
Fitment And Compatibility
Fits: Citroën C5 I (phase 1 & 2) and Citroën C5 II Estate/Tourer (models with roof/boot-mounted center brake lamp). Commonly searched under product code 6350P6. Check vehicle generation and body style (Estate/Combi/Tourer) when confirming fitment.
Function And Typical Failure Modes
The unit functions as the center high-mounted stop lamp (CHMSL), providing an additional, elevated brake signal to following traffic. Although LEDs generally offer long service life, assemblies commonly fail due to:
- Water ingress and seal deterioration leading to corrosion of contacts or circuit traces.
- Physical damage from tailgate impacts or loading of roof boxes and accessories.
- Connector oxidation or wiring chafing causing intermittent or total loss of signal.
- Thermal stress in poorly ventilated installations or where seals are compromised.
Installation Recommendations
Recommended steps for a safe and correct replacement:
- Switch ignition off and work with the rear hatch in a stable, supported position.
- Remove interior tailgate trim carefully to access the brake light assembly; watch for hidden clips and retainers.
- Disconnect the electrical connector and detach any retaining screws or clips. Note the orientation of the unit and any gaskets.
- Fit the new assembly, ensuring the sealing gasket is seated correctly to prevent water ingress. Reconnect the electrical connector and secure all fasteners to the original positions.
- Test the brake lamp function with the help of an assistant or by applying the parking brake/test mode; if the lamp does not illuminate, check fuses, connector continuity and the brake light switch.
- Replace any damaged clips or trim retainers to avoid rattles and maintain a watertight closure.

Why Replace The Unit?
Replacing the third brake light is often a quick, inexpensive repair that restores legal compliance and safety. Failure symptoms include no illumination, flickering, or water visible inside the lens. Because the lamp is mounted high and exposed to weather, seals and connectors are the most common weak points—replacing the assembly and renewing any damaged seals prevents repeat failures.
Practical Tips For Professionals
- When installing on warranty or fleet vehicles, document the work and check adjacent wiring harnesses for abrasion.
- Use dielectric grease on connectors when reassembling to reduce the risk of future corrosion.
- If fault persists after lamp replacement, verify brake light switch operation and vehicle body grounding points.
