Function

The socket secures the bulb in the rear lamp housing and provides the electrical contacts for tail, brake, indicator or reverse bulbs depending on the lamp circuit. It maintains correct positioning and contact pressure to ensure consistent illumination and signal transmission.

Compatibility And Fitment

Fits Peugeot 207 3‑ and 5‑door models from 2010 onwards equipped with LED rear lighting designs where this bulb socket is used for auxiliary filament bulbs. Designed for the left rear lamp (driver side).

How To Replace

1. Open the tailgate and remove the inner trim panel to access the rear lamp cluster.
2. Unscrew the lamp fasteners and carefully pull the lamp assembly outward.
3. Disconnect the wiring connector and remove the old bulb/socket by turning or releasing the retaining clip, depending on the lamp version.
4. Install the new socket, insert the correct bulb, reconnect the wiring harness and test the light functions before reassembling.
5. Reinstall the lamp cluster and interior trim, then verify all rear light functions on the vehicle.

Installation Recommendations

• Disconnect the negative battery terminal before starting work to avoid short circuits.
• Handle bulbs with gloves or a lint‑free cloth to prevent contamination and premature failure.
• Check the wiring connector and mating pins for corrosion or damage; clean contacts if necessary.
• Apply a thin film of dielectric grease to contacts to reduce corrosion and improve longevity.
• Ensure the lamp housing seals and gaskets are intact to prevent moisture ingress.

Most Common Failure Reasons

Sockets typically fail due to contact corrosion from moisture, heat cycling that deforms plastic or weakens contacts, mechanical damage when removing/installing bulbs, or poor electrical connection caused by oxidized pins. Water ingress or a cracked lamp housing accelerates corrosion and short circuits.

Most Common Reasons For Failure

• Water ingress due to degraded seals or damaged lens leading to corrosion of contacts or internal LEDs.
• Impact damage from minor collisions or parking knocks causing cracks or broken mounting points.
• Corroded connectors or wiring issues that interrupt the electrical supply even when the lamp itself is intact.
• Thermal stress or manufacturing defects in the LED module (less common than with incandescent bulbs).

Practical Tips

When replacing the lamp, always check the condition of the mounting gaskets and wiring harness. Clean or replace corroded connectors and apply dielectric grease on terminals to improve long-term reliability. After installation, test all light functions from both inside and outside the vehicle to ensure proper operation.
