What This Product Does

The unit combines the registration-plate lamp and reversing lamp in one assembly. Its upward-facing plate illumination distinguishes it from earlier downward-illuminating arrangements, so matching the existing installation and chassis details is important.

Functions

• Illuminates the rear registration plate.
• Provides the reversing-light function.
• Replaces the corresponding lamp assembly during repair or restoration.

Technical Details

• Brand: OE Match.
• Part reference: 64463160100.
• Combined back-up and registration-plate lamp assembly.
• Upward-illuminating configuration.
• Late 356A application: 1957–59, with separate chassis starting points for Coupe, Cabriolet and Speedster bodies.

Symptoms of Fault

• Plate illumination or reversing light does not operate consistently.
• Moisture collects within the lamp housing.
• Lens damage or clouding is visible.
• Electrical contacts show corrosion.
• Light output remains weak after the bulb and electrical connections have been checked.

Why Replacement Matters

A damaged housing, deteriorated lens or corroded internal connection can justify renewing the assembly. Diagnose the fault first: defective bulbs, wiring or earth connections can produce similar symptoms and may need attention independently. OE Match focuses on Porsche replacement applications, including components used in classic-car restoration.

FAQs

Will this fit every Porsche 356A?
No. This assembly is specified for late cars, with different chassis starting points for each body style. Use the detailed application above rather than the broader model-family dates alone.

What should be checked if the lamp works intermittently?
Inspect the bulb, contacts, wiring and earth connection, together with any signs of water entry. An intermittent fault does not automatically mean the complete assembly needs replacing.

Why might bulbs fail repeatedly?
Moisture, contact corrosion and vibration can contribute. Investigate these causes before fitting another bulb or replacement assembly.
