Description
Left Rear Lamp for PEUGEOT 406 4‑door with central trim in KMPD color. Supplied without bulb holders (sockets) — bulb holders and bulbs can be purchased separately.
Product Overview
This left rear lamp (tail light assembly) is a direct-fit replacement for Peugeot 406 4‑door models. The unit includes the outer housing and the central decorative trim in KMPD color. It controls and houses the tail, stop, and indicator lamp circuits (bulb holders/sockets and bulbs are not included). Ideal for professional workshops and DIY mechanics looking for a reliable body electrical replacement with original-equipment reference numbers for easy searching (use codes 9630364877, 6350L5, 634737).
How It Works And What It Does
The assembly provides rear illumination required for driving safety and legal compliance: running lights, brake lights and turn signal. It protects internal lamp components from road contamination and moisture when fitted correctly. Proper fitment ensures correct light alignment and electrical contact with the vehicle wiring harness.
Installation Recommendations
- Prepare: Park on level ground, switch off ignition and, for safety, disconnect the negative battery terminal if you will be handling connectors or using power tools.
- Access: Open the boot and remove or fold back the inner trim to reach the lamp mounting screws and electrical connector.
- Remove Old Unit: Unscrew mounting fasteners, carefully unclip the lamp from the body, and disconnect the wiring harness. Inspect the connector and wiring for corrosion or damage.
- Fit New Unit: Position the replacement lamp, connect the wiring harness, and secure mounting screws to factory alignment. Ensure the seal/gasket sits flush to prevent water ingress.
- Check: Reconnect the battery (if disconnected) and test all lamp functions (running, brake, indicator, reverse if applicable) before reassembling the trim.
- Tools: Common tools needed include a socket set, screwdriver/Torx driver set, and plastic trim tools to avoid damaging interior panels.
Most Common Failure Causes
- Impact Damage: Rear collisions or bumps commonly crack the lens or break mounting tabs.
- Water Ingress: Failed seals or damaged gaskets allow moisture into the housing, causing short circuits and corrosion of contacts.
- Corroded Contacts/Sockets: Age and exposure lead to poor electrical contact and intermittent operation.
- Heat Damage: Incorrect bulbs or poor ventilation can deform sockets or lens areas.
- Mechanical Fatigue: Broken clips or threaded studs from repeated removal or overtightening.
