License / number plate light bulb holder. Porsche 356 B/C  ›  64463160100

The OE MATCH License / Number Plate Light Bulb Holder 64463160100/1 is an OE-style replacement lighting component designed for Porsche 356 B and 356 C models manufactured between 1959 and 1965.

• Porsche 356 B/C 1.6L 01/59-12/65

This bulb holder forms part of the rear number plate lighting system, providing a secure mounting position and electrical contact for the bulb responsible for illuminating the vehicle's registration plate.

Designed to replace an aged, corroded or damaged original component, the OE MATCH bulb holder helps restore reliable electrical contact and correct bulb positioning within the number plate lamp assembly.

The rear number plate light is exposed to moisture, road spray, temperature changes and vibration throughout normal vehicle operation. Over time, these conditions can cause corrosion, weakened electrical contacts or deterioration of the bulb holder.

A damaged holder may result in intermittent illumination, flickering, poor bulb contact or complete failure of the number plate light.

The OE MATCH replacement provides a practical solution for restoring the original lighting arrangement without replacing the complete lamp assembly when the surrounding components remain serviceable.

Ideal for electrical repairs, rear lighting refurbishment and classic Porsche restoration projects, this replacement bulb holder helps maintain dependable registration plate illumination while preserving the factory-style appearance of the Porsche 356.

The number plate light bulb holder supports the bulb within the rear registration plate lamp assembly and provides the necessary electrical contact for illumination.

It helps keep the bulb correctly positioned while maintaining a secure connection to the vehicle's lighting circuit.

Its key functions include:

• Bulb Retention: Holds the number plate light bulb securely in its designated position.
• Electrical Connection: Provides the contact interface needed to deliver electrical power to the bulb.
• Reliable Illumination: Supports consistent operation of the rear registration plate light.
• Correct Bulb Positioning: Helps maintain the intended position of the bulb within the lamp assembly.
• Vibration Resistance: Helps minimise unwanted bulb movement during normal driving.
• Electrical Contact Stability: Maintains contact between the bulb and its associated electrical connections.
• Lighting System Maintenance: Allows a damaged or corroded bulb holder to be replaced without necessarily changing the entire lamp assembly.
• Original Equipment Styling: Supports the factory-style rear number plate lighting arrangement.
• Restoration Support: Provides a replacement component for refurbishing the original lamp assembly.
• Roadworthiness: Helps maintain the registration plate illumination required for safe and legally compliant road use.

Common symptoms include:

• Number Plate Light Not Working: A failed or heavily corroded contact may prevent the bulb from illuminating.
• Intermittent Illumination: The light may operate inconsistently if the bulb holder has loose or deteriorated electrical contacts.
• Flickering Light: Poor contact between the bulb and holder may cause flickering, particularly when driving over uneven surfaces.
• Corroded Electrical Contacts: Green, white or dark deposits around metal contact surfaces may indicate corrosion.
• Loose Bulb Fitment: Worn or damaged retaining contacts may prevent the bulb from remaining securely positioned.
• Discoloured or Heat-Damaged Holder: Excessive resistance, an incorrect bulb or poor contact may cause localised overheating.
• Visible Cracks or Breakage: Physical damage may affect the holder's ability to support the bulb securely.
• Burnt or Pitted Contacts: Electrical arcing or prolonged poor contact may leave damaged contact surfaces.
• Bulb Movement or Rattling: A weakened holder may allow the bulb to move within the lamp assembly.
• Moisture Inside the Lamp: Water ingress may accelerate corrosion of the bulb holder and associated electrical connections.
• Repeated Lighting Problems: Persistent faults despite fitting a working bulb may indicate problems with the holder, wiring or earth connection.
• Damaged Wiring Connections: Loose, oxidised or damaged terminals around the holder may interrupt electrical supply.
• Difficult Bulb Installation: A bent, corroded or distorted holder may prevent the bulb from seating correctly.

• Replacing a worn, damaged or corroded number plate light bulb holder is an important part of maintaining the reliability and correct operation of your classic Porsche 356's rear lighting system.
• The bulb holder provides the electrical connection required for the number plate lamp to operate. If the holder becomes corroded or its contacts lose their tension, the electrical circuit may become unreliable.
• This can result in flickering, intermittent illumination or complete failure of the registration plate light.
• Reliable number plate illumination is important for night-time visibility and compliance with applicable roadworthiness regulations.
• A defective bulb holder can also contribute to repeated lighting problems, even when the bulb itself is in good condition.
• Corroded or loose electrical contacts may create increased resistance, potentially leading to heat build-up and further deterioration of the surrounding electrical components.
• Replacing the damaged holder helps restore secure bulb retention and a dependable electrical connection.
• The number plate lamp assembly is also exposed to rainwater, road spray and environmental contamination. If the lamp's seals have deteriorated, moisture can enter the housing and accelerate corrosion of the internal bulb holder.
• When replacing the bulb holder, inspecting and renewing damaged lamp gaskets can help prevent the same problem from recurring.
• For classic Porsche restoration projects, maintaining the original-style rear lighting arrangement is important for preserving the vehicle's appearance and authenticity.
• The OE MATCH replacement allows the bulb holder to be renewed while retaining other serviceable components of the original lamp assembly.
• This can be a practical and cost-effective alternative to replacing the complete number plate lamp.
• The OE MATCH License / Number Plate Light Bulb Holder 64463160100/1 provides a suitable replacement solution for restoring reliable bulb contact, maintaining correct lamp operation and protecting the functionality of the Porsche 356 rear registration plate lighting system.
