Description
Right Rear Tail Light For Citroën C8 Vehicles
This right rear tail light assembly is intended for Citroën C8 models and is commonly identified by product code 6351Y5. It is a rear combination lamp that provides essential lighting functions for safe driving and legal road use. Frequently searched under code 6351Y5 (and related references), this part is suitable for professional workshops and experienced DIY mechanics who perform body-electrical repairs and replacements.
The assembly typically covers the essential rear light functions: tail/parking light and brake light, plus turn signal. Depending on the vehicle specification, reverse or rear fog functions may be integrated in the same unit or fitted separately. Replacing the complete lamp is the recommended solution when the housing is cracked, lenses are fogged, or internal seals have failed, as these issues often lead to recurring electrical faults.
Technical Information
- Manufacturer: Citroën (Stellantis)
- Model: Citroën C8 (compatible with related Stellantis MPV platforms; check fitment by product code)
- Product Codes: 6351Y5, NFP
- Other Numbers: 6351Y55
Installation Recommendations
- Recommended Tools: Phillips or Torx screwdriver (depending on model), small socket set, trim removal tool, and gloves.
- Basic Steps: Open the tailgate, remove interior trim fasteners to access the lamp fixing screws, unfasten the retaining screws, disconnect the electrical connector, remove the lamp assembly and fit the new unit in reverse order.
- Practical Tips: Keep the vehicle ignition off while working. Inspect connector pins and wiring for corrosion; apply dielectric grease to connectors to slow future corrosion. Ensure the lamp gasket sits evenly to maintain water tightness. Test all light functions (tail, brake, indicator and reverse if applicable) before reassembling interior trim.
- When To Replace: Replace the entire assembly if the lens is cracked, sealant is degraded, or internal condensation appears — simple bulb swaps will not fix housing or sealing failures.
Most Common Failure Causes
- Impact Damage: Rear collisions or minor parking impacts that crack the lens or deform the housing.
- Moisture Ingress: Failed seals or cracks allow water into the lamp, causing corrosion, short circuits or fogging.
- Connector And Wiring Corrosion: Salt, moisture and age can corrode pins and sockets, causing intermittent operation.
- Bulb Burnout Or Socket Wear: Individual bulbs may fail over time; however, recurring electrical issues usually indicate housing or connector problems.
- Vibration And Fatigue: Long-term vibration can loosen fixings or create hairline cracks in the lens or mounting points.
Buying Tip: This part is often searched by product code 6351Y5. When replacing a damaged rear lamp assembly, prefer a full assembly swap if the housing, seals or connectors show damage — this ensures reliable operation and restores correct light optics.
