Description

High-quality replacement bulb holder (socket) designed for the right rear lamp of the Peugeot 3008 T84. The part includes a short wiring pigtail to simplify installation and ensure reliable electrical connection to the vehicle harness. Ideal for professional workshops and DIY mechanics who need a direct-fit solution for a failed or corroded lamp socket.

Function And Fitment

This socket is intended to secure and supply power to a P21/5W dual-filament bulb used in the right rear lamp assembly (tail/stop light). It provides the mechanical seating and electrical contacts necessary for stable filament operation and proper lighting function. Fitment: Peugeot 3008 I (T84).

Technical Information

• Manufacturer: Stellantis / Peugeot
• Model: Peugeot 3008 I (T84)
• Product Codes: 9683460780, 6351HC, 6351.HC
• Additional Numbers: P21/5W

Installation Recommendations

• Park the vehicle on a level surface and switch off all lights before starting work.
• Access the rear lamp assembly from the boot/boot trim or by removing the lamp cluster as required by the vehicle bodywork.
• Disconnect the lamp wiring connector, remove the old socket by turning or unclipping it from the lamp holder, and disconnect any retaining clips.
• Compare the new socket and pigtail with the removed part to confirm matching contacts and bulb type (P21/5W).
• Install the new socket into the lamp cluster, secure any clips, reconnect the wiring harness, and fit the bulb.
• Test the lamp functions (tail, stop, indicator if applicable) before reassembling trims. Use dielectric grease on contacts to improve protection against corrosion where appropriate.
• Ensure all seals and gaskets are correctly positioned to prevent water ingress into the lamp housing.

Why This Part Fails Most Often

Rear lamp sockets typically fail due to corrosion of the contacts, heat damage from the bulb (melting or distortion of the plastic), mechanical wear from repeated bulb changes, water ingress into the lamp housing, or poor electrical connection caused by oxidized terminals. Vibration and road salt accelerate deterioration, especially on older vehicles.

Service Life And Replacement Advice

There is no fixed mileage interval for socket replacement. Replace the socket when you observe intermittent lamp function, visible corrosion, melted plastic, loose contacts, or when the lamp assembly shows signs of water entry. Replacing a damaged socket promptly prevents further electrical problems and avoids blown bulbs or lamp failure warnings.

Installation Recommendations

• Access the tail lamp from inside the luggage compartment: remove the trim panel to reach the lamp retaining screws or clips.
• Unscrew or unclip the fasteners, carefully pull the lamp assembly away from the body, and disconnect the wiring harness plug(s).
• Fit the new lamp into the body aperture, ensuring the sealing gasket seats correctly to prevent water ingress. Reconnect the wiring and secure the lamp with the original fasteners at correct torque.
• Replace bulb holders if not supplied and test all light functions (tail, stop, indicator, reverse if applicable) before reassembling interior trim.
• Always disconnect the negative battery terminal before working on vehicle electrics to avoid short circuits or damage to on‑board electronics.

Why The Part Fails Most Often

• Water Ingress And Condensation: Failed seals or cracks allow moisture to enter, causing corrosion, short circuits or fogging that reduces light output.
• Impact Damage: Rear collisions or minor bumps commonly crack the lens or break mounting points, making replacement necessary.
• Connector And Wiring Corrosion: Long‑term exposure to road salts and moisture can corrode pins and sockets, leading to intermittent or failed contacts.
• Bulb Holder Wear: Bulb sockets and clips degrade over time from heat cycles; if holders are missing or damaged, the lamp will not function until replaced.

Replacing the lamp restores both safety and appearance. For an efficient repair, use original or OEM‑equivalent bulb holders and ensure seals are intact to prevent repeat failures. This part is often searched by part number (9683460780 / 6351HC), so matching codes will speed up identification and ordering.
