Fitment And Function

This right rear lamp provides stop/tail/indicator/reverse functions as applicable to the Peugeot 407 Sedan rear lighting cluster. The assembly is designed to mount to factory points on the boot lid and body, with standard Peugeot multi-pin connector. Always confirm that the connector pinout and lamp functions match the vehicle wiring harness before final installation.

Installation Recommendations

• Before starting, disconnect the vehicle battery to prevent short circuits and accidental bulb activation.
• Open the boot and remove the interior trim panel/access cover to reach the lamp fixing screws and electrical connector.
• Disconnect the wiring harness by unclipping the connector and carefully release any retainer clips.
• Remove the fixing nuts or screws securing the lamp, withdraw the assembly, and transfer any required bulbs or gaskets if applicable.
• Fit the replacement lamp into position, secure fasteners evenly to avoid stressing mounting tabs, reconnect the harness and test all lamp functions (tail, brake, indicator, reverse).
• Check sealing surfaces and replace worn gaskets or seals to prevent moisture ingress. Tighten fasteners to a firm, even seating—do not overtighten plastic studs.

Why This Part Fails

• Impact Damage: Rear-end collisions or minor bumps commonly crack the lens or break mounting tabs.
• Moisture Ingress: Failed seals allow water into the housing, causing corrosion of contacts and bulb failure.
• UV Degradation: Long-term sun exposure can make the lens brittle and discolored.
• Connector Or Socket Corrosion: Corroded contacts lead to intermittent operation or complete failure of light functions.
• Vibration And Fatigue: Repeated stress can break mounting points or internal lamp holders over many years.

Practical Tips For Mechanics And DIYers

• Verify whether bulbs and rubber seals are included with the assembly; replace bulbs if they show signs of age or corrosion.
• When replacing a lamp after water ingress, clean and dry the cavity thoroughly and inspect the harness for corrosion—repair wiring or connectors as needed.
• Keep replacement mounting clips and gaskets on hand; plastic fasteners commonly snap during disassembly on older vehicles.
