Compatibility And Fitment
Intended for the right rear inner tailgate lamp of Peugeot 406 Estate (Combi) models. Often searched and identified by the product code 6351H6. Verify fitment visually against the original socket and connector style before installation.
Function And Common Faults
The socket secures the bulb and provides electrical contact for the tailgate inner lamp (reverse/boot light or courtesy lamp depending on vehicle wiring). Common reasons for failure include corrosion from moisture ingress, heat damage from old bulbs, brittle plastic after long-term exposure, and connector or wiring fatigue. Failure symptoms are intermittent lighting, no light at all in the lamp position, blown fuses, or visible discoloration/melting of the socket.
Replacement Procedure
Basic steps for replacing the right rear tailgate inner lamp socket. Suitable for experienced DIYers and professional mechanics:
- Prepare Tools: Trim tools, flat screwdriver, pliers, electrical contact cleaner, new bulbs if necessary.
- Safety First: Disconnect the negative battery terminal before starting work to avoid short circuits while handling wiring.
- Access Lamp Assembly: Open tailgate, remove interior trim or access cover to reach the lamp housing.
- Remove Lamp Housing: Unscrew or unclip the lamp unit from the tailgate carefully.
- Disconnect Socket: Unplug the wiring connector and remove the old socket from the lamp housing. Cut damaged wires only if necessary and strip/crimp new connections accordingly.
- Install New Socket: Fit the new 6351H6 socket into the lamp housing, reconnect wiring, and use dielectric grease on contacts if available to reduce corrosion risk.
- Test Function: Reconnect the battery, test the lamp operation, then reassemble trim and secure all fasteners.
Installation Recommendations
Use correct-sized bulbs and inspect bulb holders for signs of overheating. Replace bulbs when installing the new socket to ensure reliable contact and prevent premature socket damage. Protect electrical contacts with dielectric grease and route the wiring away from pinch points. If wiring insulation is damaged, repair with heat-shrink tubing and proper connectors. For professional installations, use torque settings and fasteners recommended by the vehicle manufacturer.
Why This Part Commonly Fails
The socket is exposed to vibration, heat from bulbs and occasional moisture when the tailgate seal ages. Plastic becomes brittle over time and contacts corrode, leading to poor electrical contact or failure. Repeated bulb overheating or using incorrect bulbs accelerates degradation. Regular inspection during tailgate trim work helps detect wear early.
Notes For Buyers
This listing targets mechanics and competent DIY owners who search by part number (6351H6). The part is supplied with wiring as described. Replace bulbs when fitted to ensure optimal long-term performance.
