Description
Third rear brake light for Citroën C5 II hatchback. Tested, fully functional.
Product Overview
This third brake light (center high-mounted stop lamp) is designed for the Citroën C5 II hatchback and carries OEM references 6350N9 / 6351EV. It provides a clear, high-mounted stop signal that improves visibility to following traffic and contributes to overall road safety. The unit is suitable for professional workshops and experienced DIY mechanics who perform body and lighting repairs.
Why This Part Matters
The center brake light is a critical safety component: it gives a high, eye-level indication of braking that is especially visible to drivers behind taller vehicles. A worn or damaged third brake light can reduce visibility, increase the risk of rear-end collisions, and will typically lead to a bulb/lighting fault warning or MOT/test failure in many countries.

Installation Guide
Installation is straightforward for trained mechanics and competent DIYers with basic tools. Typical replacement steps:
- Open the tailgate and remove the inner trim panel to access the lamp housing.
- Disconnect the electrical connector from the lamp (ensure ignition off; it is good practice to disconnect the negative battery terminal when working on vehicle electrics).
- Remove fasteners (screws/clips) securing the lamp assembly and withdraw the unit from the tailgate.
- Install the replacement lamp, secure fasteners, reconnect the electrical connector and refit the trim panel.
- Test the brake lamp operation with the help of an assistant or by engaging the parking brake and applying the brake pedal.
If the unit contains replaceable bulbs, inspect and replace bulbs as required. If fitted with an LED module, handle the unit carefully to avoid damaging the PCB or lens.
Recommended Workshop Tips
- Use trim tools to avoid damaging interior panels when removing the tailgate trim.
- Check connector pins for corrosion and apply contact cleaner if necessary before reconnection.
- After installation, confirm there are no fault codes related to the lighting circuit and verify correct lamp brightness and alignment.
Most Common Failure Causes
Third brake lights typically fail due to one or more of the following reasons:
- Water Ingress: Seal failure or cracks allow moisture into the housing, causing corrosion and electrical faults.
- Connector Corrosion: Exposed or aged connectors develop poor contact and intermittent function.
- Bulb Failure or LED Degradation: Traditional filament bulbs burn out; LEDs can fail due to heat or solder joint fatigue.
- Physical Damage: Impacts to the tailgate or lens cracking from external forces.
Notes For Buyers
This listing contains the product codes 6350N9 and 6351EV—match these codes and the unit shape with your vehicle before ordering. The part is intended for professionals and skilled enthusiasts comfortable with moderate disassembly of the tailgate interior.
