Description
Right rear tail light for Citroën C8 vehicles.
This right-hand rear tail light assembly is a direct-fit replacement designed for Citroën C8 owners and professional garages. It restores rear lighting functions and exterior appearance after collision damage, lens cracking or electrical faults. The part is commonly searched by its product code, making it easy to find and order for quick repairs.
Fitment And Application
Fits Citroën C8 and compatible MPV models from the same Stellantis platform (for example Peugeot 807). Confirm fitment by matching the product code 6351Y5 with your existing lamp. The assembly is intended for the right-hand side of the vehicle (rear passenger side in left-hand-drive cars).
Function And Benefits
The lamp performs essential rear lighting duties including rear position and stop functions and turn signal indication as integrated in a single housing. Replacing a damaged or faded lamp restores light output, safety and legal compliance, and prevents water ingress that can lead to electrical faults.
Installation Recommendations
- Disconnect the battery before starting work to avoid short circuits when handling connectors.
- Open the rear tailgate and remove the interior trim panel to access the lamp mounting screws or nuts.
- Unscrew the fasteners, carefully pull the lamp outwards and disconnect the wiring harness by releasing the connector clip.
- Compare the new assembly with the old unit to ensure matching lamp sockets and connector positions, then connect the harness and secure the lamp with original fasteners.
- Check seals and replace any damaged gaskets to prevent moisture ingress. Test all light functions (position, brake, indicator) after installation.
Most Common Reasons For Failure
- Water Ingress And Condensation: Damaged seals or cracked lenses allow moisture to enter, causing corrosion and short circuits.
- Impact Damage: Rear-end collisions or bumps often crack the lens or housing, necessitating lamp replacement.
- Corroded Connectors: Corrosion at bulb holders or wiring connectors can interrupt circuits and cause intermittent lighting.
- Bulb Or Socket Wear: Repeated bulb replacements and heat cycles can degrade sockets or filaments.
