Description
Third additional brake light for CITROËN C4 Coupé first series. Before purchase, make sure you do not have a damaged supply cable on the vehicle. Tested fully functional.
Product Description
This high-mounted third brake light (center high-mounted stop lamp, CHMSL) is intended for Citroën C4 Coupé first series vehicles and is commonly searched by OEM numbers 9650812280 and 6351V2. Designed for mechanics and experienced DIYers, the unit restores proper brake-light visibility at the rear centre of the vehicle and helps meet road-safety requirements. Searching by product code is common among professionals, so the OE references are included to simplify identification and ordering.
Function And Fitment
The third brake light provides an additional, centrally located stop signal that improves vehicle visibility to drivers behind, especially under braking. Correct operation is important for safety and for passing vehicle inspections. This unit fits Citroën C4 Coupé (First Generation) models; check the OEM codes 9650812280 / 6351V2 against the vehicle parts list when confirming fitment.
How To Replace
Replacement is straightforward for a trained technician or a competent DIY mechanic. Typical steps:
- Access the lamp from the trunk or rear parcel shelf by removing the interior trim to reach the mounting screws and wiring connector.
- Disconnect the electrical connector carefully and remove the fixing screws or clips securing the lamp assembly.
- Remove the old lamp and compare the connector and mounting points with the replacement to ensure correct orientation.
- Install the new unit, secure fasteners, reconnect the wiring and re-fit interior trim.
- Test brake light operation with the help of an assistant or by applying the parking brake while observing the lamp.
Installation Recommendation
Work Should Be Performed By A Qualified Technician Or An Experienced DIY Mechanic. Before disconnecting any connectors, isolate the vehicle’s electrical system to avoid short circuits—disconnect the negative battery terminal if appropriate for the job. Take care when removing trim panels to avoid breaking plastic clips. Inspect the wiring harness and connector for corrosion or damage before installation and apply dielectric grease to connectors where appropriate to prevent future corrosion. After installation, verify proper illumination and secure fitment.
Why This Part Commonly Fails
Common failure causes include water ingress leading to corrosion of contacts or LED/modules, physical damage from impacts or stress on the mounting points, and connector or wiring harness wear (often caused by repeated hatch/trunk movement). In vehicles with bulb-type CHMSL, filament burnout is possible; in LED-type modules the failure is more often due to moisture or internal electronic faults.
