Installation Recommendations
Install from the luggage compartment side by removing the interior trim panel to access the lamp housing. Remove the retaining screws or clips, unplug the electrical connector and withdraw the lamp assembly. Fit the new assembly into the mounting bracket, secure fasteners evenly to avoid stress on mounting tabs, reconnect the electrical plug and test the lamp function before refitting trim. Apply a small amount of dielectric grease to the connector pins to reduce the risk of future corrosion. If the bulb is not working on delivery, replace it with the correct bulb type and ensure the socket is clean and undamaged.
Common Failure Reasons
Rear fog lamps typically fail due to water ingress and corrosion of the contacts or socket, impact damage when reversing, cracked housings from road debris or minor collisions, or simply bulb burnout. Corroded connectors and damaged mounting tabs are frequent causes that necessitate replacement of the complete assembly rather than just the bulb.
Searchable by OE numbers 9646507380 and 6351T4, this unit is a convenient spare for workshops and owners maintaining Peugeot 407 SW vehicles. Replacing a damaged fog lamp restores rear visibility in adverse conditions and keeps the vehicle compliant with road safety regulations.
