Description
Bulb holder with a section of wiring for the right rear lamp of Peugeot 407 saloon up to 2008. Functionality of the bulbs themselves is not guaranteed.
Product Overview
Right rear lamp bulb holder with a short pigtail harness, suitable for Peugeot 407 saloon models (up to 2008). This replacement socket provides the mechanical and electrical interface between the vehicle wiring and the tail lamp bulbs (stop/taillight, indicator, reverse as applicable) and is a common service item when the original holder suffers corrosion, melted plastic or damaged wiring.
Why This Part Is Useful
- Restores reliable electrical contact in the tail lamp circuit when pins are corroded or wiring is damaged.
- Speeds up repair compared with rewiring the entire harness—bolt-in replacement for the socket and pigtail section.
- Ideal for professional workshops and competent DIY mechanics who perform targeted lamp repairs.

Function And Common Faults
The socket secures the bulbs and provides the electrical contacts that feed the filaments. The most frequent failure modes are contact corrosion caused by moisture ingress, overheating or short circuits that deform the plastic, and brittle or broken wires at the pigtail strain points. Symptoms are intermittent or non-functioning stop/tail/indicator lights, blown fuses, or visible heat damage in the lamp housing.
Replacement Frequency And Durability
There is no fixed replacement interval; life expectancy depends on local climate, exposure to moisture and previous repairs. In coastal or winter-salted environments the contact pins may corrode within a few years. Heat damage from poor bulb seating or overloaded circuits accelerates failure.
Installation Recommendations
Recommended for experienced technicians and competent DIYers. Typical replacement steps:
- Disconnect the negative battery terminal before starting to avoid shorts and protect vehicle electronics.
- Open the boot and remove the tail lamp cluster retaining screws or clips according to the vehicle trim.
- Withdraw the lamp assembly to access the bulb holder; unplug the original connector from the vehicle harness if present.
- Remove the old bulb holder from the lamp housing by turning or unclipping bulbs and holder as required.
- Fit the new socket into the lamp housing, secure bulbs in place and route the pigtail so it is free from pinch points.
- Reconnect wiring, secure any retained fasteners and test all lamp functions (stop, tail, indicator, reverse) before refitting covers.
- Use dielectric grease on contacts to reduce future corrosion and ensure tight mechanical fixing to prevent vibration-related failures.
Why The Part Usually Fails
Most common causes are water ingress into the lamp housing and corrosive attack on the contacts, thermal degradation from overheated bulbs or poor contact, and mechanical fatigue at the wiring termination. Faulty seals or previous condensation inside the lamp are frequent contributors.
Notes For Professionals
Inspect the lamp housing for cracks and the vehicle-side connector for similar damage before fitting a new socket. If wires on the vehicle harness are brittle or short, consider extending or reterminating the pigtail to a healthy wiring section using correct crimping/soldering and insulation methods.
Compatibility
Designed for Peugeot 407 saloon rear right lamp applications up to 2008 where the original socket design corresponds to the 6351GE specification. Verify physical fitment against the removed part before final installation.
