Fitment
Designed For Rear Outer Lamp Assembly On Peugeot 406 Estate (Combi). Verify Side Carefully Against Original Part; the original long description specifies the left side.
Replacement Procedure (Recommended)
- Park The Vehicle On A Stable Surface And Disconnect The Negative Battery Terminal To Avoid Short Circuits When Working On Wiring.
- Remove The Rear Lamp Unit From The Wing According To The Vehicle Manufacturer’s Procedure (Access Screws/Clips From Inside The Tailgate Or Boot Area).
- Unplug The Existing Bulb Holder And Cut Back Any Damaged Wiring If Necessary.
- Fit The New Socket And Connect The Supplied Pigtail, Preferably Using Crimp Connectors Or Soldering With Heat-Shrink Insulation For A Durable, Weatherproof Joint.
- Apply A Thin Layer Of Dielectric Grease To Contacts To Reduce Corrosion Risk.
- Refit The Lamp Assembly, Test All Functions (Brake, Tail, Indicator) And Secure All Fasteners.
Installation Recommendations
- Use Proper Crimping Tools Or Solder Joints With Heat-Shrink Tubing For Long-Term Reliability.
- Replace Bulbs When Replacing The Socket To Ensure Good Contact And Avoid Early Failures.
- Seal Wire Penetrations And Lamp Seals To Prevent Moisture Ingress.
- Inspect Lamp Housing For Cracks Or Broken Seals That Could Allow Water To Reach The Socket.
Why This Part Fails
Bulb holders and sockets typically fail because of moisture ingress and corrosion of the contacts, vibration-induced wear, thermal cycling from repeated bulb heating and cooling, or brittle plastic that cracks with age. Poor electrical contact causes flickering or intermittent lighting and can lead to increased resistance and heat, accelerating damage. Replacing the socket and correcting sealing or wiring issues prevents repeat failures.
Practical Notes For Mechanics And DIYers
- Search By Product Code 6351H5 To Locate The Correct Socket Quickly.
- Keep A Stock Of Common Bulbs And Heat-Shrink Tubing For Efficient Repair Jobs.
- When In Doubt About Corroded Wiring Upstream, Trace And Repair The Affected Section Rather Than Only Replacing The Socket.
