This replacement bulb socket is designed for mechanics and DIY enthusiasts who need a reliable solution for a worn or damaged tailgate inner lamp on the Peugeot 406 Estate. The part restores proper electrical contact and secure bulb seating in the tailgate lamp assembly, and it comes with a short length of wiring to simplify installation. Commonly searched under the code 6350H6, this socket is an economical way to eliminate flickering lamps, intermittent contact or failures caused by corrosion and connector wear.
Technical Information

- Model: Peugeot 406 Estate (Combi)
- Product Codes: 6350H6, 6350H6 NFP
- Additional Numbers: Not Specified
Function And Benefits
The socket secures the bulb inside the left rear inner lamp assembly and provides the electrical connection between the bulb and the vehicle wiring harness. Replacing a degraded socket restores stable contact, prevents intermittent lighting faults, and reduces the risk of increased resistance and heat build-up. Supplied wiring helps bypass damaged pigtails, making the repair quicker and more reliable.
Recommended Installation
- Remove the tailgate inner trim to access the lamp housing.
- Disconnect the lamp connector and remove the old socket from the lamp housing.
- If necessary, cut back damaged wiring and use the supplied pigtail to make a secure connection (solder or use proper crimp connectors) and insulate with heat-shrink tubing.
- Fit the new socket into the lamp housing, install new bulbs (recommended) and reconnect the connector.
- Test lamp function (side, brake, or reversing light as applicable) before reassembling the trim.
- Use dielectric grease on contacts to reduce future corrosion and ensure a long-lasting connection.
Why This Part Most Commonly Fails
Failure is typically caused by moisture ingress and corrosion of the socket contacts, mechanical wear from repeated bulb changes, or wiring fatigue in the tailgate flex section. Heat cycles from the bulb and poor contact can accelerate deterioration, leading to flickering, intermittent operation or complete loss of the lamp. Replacing both the socket and the bulbs at the same time reduces the chance of early recurrence.
Practical Tips For Professionals And DIYers
- Always use quality connectors and proper insulation to prevent future faults.
- Check the surrounding lamp housing for cracks or seals that allow water entry and repair if needed.
- When repairing the tailgate wiring harness, support and protect the cable to prevent chafing at hinge points.
