Description
Bulb holder with a short length of wiring for the right rear lamp on Peugeot 407 sedan up to 2008. Functionality of the bulbs themselves is not guaranteed.
Overview
This replacement right rear lamp socket with attached wiring harness is designed for Peugeot 407 sedan models (manufactured up to 2008). It provides a direct mechanical and electrical interface between the vehicle wiring and the rear combination lamp, allowing tail, brake, indicator or reversing bulb circuits (depending on lamp version) to be connected securely. Commonly searched under the code 6351GE, this part is ideal for professional workshops and experienced DIY mechanics looking to repair damaged sockets or intermittent rear light faults.
Why Replace This Part
The lamp socket and short wiring pigtail are subject to heat cycles, moisture ingress and mechanical stress. Corrosion of the contacts, cracked plastic, melted insulation or damaged locking tabs are the typical failure modes that cause flickering lights, intermittent loss of a filament circuit or complete open circuit. Replacing the socket restores reliable contact and simplifies further diagnosis compared with trying to repair brittle connectors.
Fitment And Compatibility
Fits: Peugeot 407 Sedan (model years up to 2008). Product code often used in searches: 6351GE. Verify lamp version visually when ordering: sockets may vary slightly between different rear lamp assemblies (e.g. with or without reversing lamp/indicator positions).
How To Replace
Basic replacement steps for a competent mechanic or experienced DIYer:
- Open the boot and remove the trim or access panel to reach the rear lamp assembly.
- Unscrew or release the lamp cluster fasteners and pull the lamp assembly out enough to access the bulb holder.
- Unplug the old socket from the lamp cluster and release any retaining clips. If necessary, cut the pigtail close to the damaged portion for replacement with the supplied harness.
- Install the new socket into the lamp cluster, ensuring correct orientation and secure locking of tabs.
- Reconnect the wiring harness and test all rear light functions (tail, brake, indicator, reversing) before reassembling the lamp cluster.
- Reinstall the lamp assembly and any trim, and verify that all connections are secure and waterproofing is intact.
Installation Recommendations
- Inspect wiring and the lamp housing for corrosion or water ingress; if present, address sealing issues to prevent repeat failure.
- Use dielectric grease on contacts to slow future corrosion and improve conductivity.
- Check bulbs and their filaments before final assembly—this part does not guarantee bulb functionality.
- If any wiring or insulation is damaged beyond the pigtail, extend or repair wiring using correct gauge, heat-shrink tubing and solder or approved crimp joints.
- After installation, verify operation of each circuit with the vehicle electrics energized and ensure secure mechanical fitment to avoid vibration damage.

Reason For Common Failure
The most frequent causes are contact corrosion from moisture and road salt, mechanical fatigue of the plastic socket or locking tabs, and heat damage from high-wattage bulbs or poor electrical contact. Vibration and repeated bulb changes can also wear the retaining features, leading to intermittent or lost connection.
Notes For Professionals
This part is commonly used in workshop repairs and is suitable for direct replacement of the rear lamp socket and short wiring pigtail. Always confirm lamp variant visually before ordering to ensure correct fitment. Testing with a multimeter can help identify whether the fault lies with the socket, the bulb or upstream wiring.
