Technical Information

Manufacturer: Citroën
Model: Citroën Xsara Picasso (up to 2004) — Rear Left (Driver’s Side)
Product Codes: 9631564080, 89300250, 6350N0
Additional Numbers: 6350.N0

Function And Application

The tail light assembly houses stop, tail/position and indicator lighting elements and provides the correct optical alignment required for road safety and legal compliance. It is manufactured to match the original lens geometry and mounting points, ensuring proper sealing against water and vibrations when installed correctly.

Replacement Notes — How To Replace

Suitable for professional fitment or experienced DIY installers. General replacement steps:

• Open the rear hatch and remove the inner trim panel or access cover to reach the lamp fasteners.
• Unscrew or unclip the fasteners securing the lamp assembly and carefully pull the unit outward a few centimeters.
• Disconnect the electrical connector and remove the lamp from the body.
• Fit the new lamp ensuring the sealing surface is clean and undamaged, reconnect the electrical plug and secure the fasteners.
• Restore the interior trim and check all light functions (tail, stop, indicator) before returning the vehicle to service.

Recommended Tools And Tips

Common hand tools are sufficient: screwdrivers or socket set to remove fasteners, trim tools to avoid damaging panels, and a clean cloth to prepare sealing surfaces. After installation verify bulb seating and connector contact. Replace faulty bulbs or corroded sockets at the same time to prevent intermittent faults.

Why This Part Commonly Fails

Tail light failures on older Xsara Picasso models are usually caused by one or more of the following:

• Water ingress and condensation leading to corrosion of bulb holders and connectors.
• Impact damage to the lens or mounting tabs from minor collisions.
• Age-related degradation of internal seals and gaskets allowing moisture entry.
• Wear or corrosion of electrical contacts causing intermittent or non-functional lamps.

Installation Recommendations

Handle the new lamp by the housing and avoid touching bulbs with bare hands. Ensure mating surfaces are clean and dry and that the lamp is seated evenly before tightening fasteners. If connector terminals show corrosion, clean or replace them to ensure a reliable electrical connection. Test all light functions after installation and secure any loose wiring to prevent chafing.

Suitable For

Citroën Xsara Picasso models manufactured up to 2004 requiring a rear left tail lamp with OE reference numbers 9631564080 / 89300250 / 6350N0.
