Number plate light glass. Porsche 356B / 356C  ›  64463161105

The OE MATCH License / Number Plate Light Glass is a replacement lighting lens designed for Porsche 356 B and 356 C models manufactured between 1959 and 1965.

• Porsche 356 B/C 1.6L 01/59-12/65

Designed to provide OE-style fitment, appearance and functionality, this replacement glass forms part of the rear number plate illumination assembly, helping protect the bulb and associated electrical components while allowing light to pass through and illuminate the vehicle's registration plate.

Also known as a number plate lamp lens or licence plate light glass, this component helps maintain the original appearance and performance of the Porsche 356 rear lighting system.

Over time, exposure to road debris, moisture, temperature fluctuations and general ageing can cause the original glass to become cracked, chipped, scratched or damaged. A deteriorated lens may reduce the quality of number plate illumination and allow moisture or contaminants to enter the lamp housing.

The OE MATCH License / Number Plate Light Glass provides a practical replacement solution for restoring the original lighting arrangement without replacing the complete number plate lamp assembly.

Ideal for routine lighting maintenance, rear bodywork refurbishment and classic Porsche restoration projects, this component helps preserve the authentic appearance and functionality of the vehicle's rear registration plate lighting system.

What This Product Does:
The number plate light glass forms the outer lens of the rear registration plate lamp assembly, allowing light from the bulb to illuminate the number plate while providing a protective barrier against environmental exposure.

Its key functions include:

• Number Plate Illumination: Allows light from the number plate bulb to pass through and illuminate the rear registration plate.
• Light Distribution: Helps provide appropriate illumination across the number plate when installed within the correct lamp assembly.
• Bulb Protection: Provides a protective barrier between the lamp's internal components and the external environment.
• Moisture Protection: Works with the associated sealing gasket to help prevent rainwater and road spray from entering the lamp housing.
• Dust and Dirt Protection: Helps reduce the accumulation of road dirt, dust and debris around the bulb and electrical connections.
• Electrical Component Protection: Helps shield the bulb holder and wiring connections from external contamination.
• Original Appearance: Maintains the factory-style appearance of the classic Porsche 356 rear number plate lighting assembly.
• Lighting System Reliability: Supports consistent number plate illumination by maintaining an intact protective lens.
• Roadworthiness Support: Helps maintain effective registration plate illumination for night-time visibility and applicable roadworthiness requirements.
• OE-Style Replacement: Restores the original lamp lens arrangement without requiring replacement of the complete assembly.

Common signs include:

• Cracked or Broken Glass: Visible cracks or fractures may compromise the lens and allow moisture or dirt to enter the lamp assembly.
• Chipped or Damaged Edges: Damage around the edges of the glass may prevent correct seating within the lamp housing.
• Scratched Lens Surface: Heavy scratching or surface wear can affect the appearance and clarity of the number plate light.
• Reduced Number Plate Illumination: A heavily damaged or contaminated lens may reduce the amount of light reaching the registration plate.
• Water Ingress: A cracked lens or poor sealing contact may allow rainwater and road spray to enter the lighting assembly.
• Condensation Inside the Lamp: Moisture collecting behind the glass may indicate a damaged lens, deteriorated gasket or poorly sealed housing.
• Loose or Rattling Glass: Damaged retaining points or incorrectly fitted components may allow unwanted lens movement.
• Missing Lamp Glass: An absent lens leaves the bulb and internal electrical components exposed to moisture, dirt and physical damage.
• Corroded Bulb Holder: Moisture entering through a damaged lens may contribute to corrosion around the lamp's electrical contacts.
• Intermittent Number Plate Lighting: Moisture-related corrosion or contamination may cause unreliable electrical operation.
• Damaged Sealing Surface: Chips or uneven edges may prevent the gasket from creating an effective seal.
• Deteriorated Appearance: Cracked, scratched or damaged glass can detract from the original appearance of the vehicle's rear lighting assembly.

• Replacing a worn, cracked or damaged number plate light glass is an important part of maintaining the functionality, weather protection and original appearance of your classic Porsche 356.
• The number plate lighting system is designed to illuminate the vehicle's rear registration plate during darkness and low-light conditions. The glass lens plays an essential role by allowing light to pass through while protecting the internal lamp components from environmental exposure.
• When the original glass becomes cracked, chipped or broken, moisture and dirt may enter the lamp housing, increasing the risk of corrosion and electrical deterioration.
• Water ingress can damage the bulb holder, electrical terminals and surrounding fittings, potentially causing intermittent illumination or complete lighting failure.
• A correctly fitted replacement glass helps restore the protective enclosure of the number plate lamp, particularly when installed with a serviceable sealing gasket.
• Maintaining an intact lens also helps ensure that light passes through the assembly effectively, supporting clear and consistent registration plate illumination.
• Proper number plate lighting is important for vehicle identification and compliance with applicable roadworthiness requirements. Damaged or ineffective lighting may contribute to MOT inspection issues where it prevents the registration plate from being illuminated correctly.
• Replacing a damaged lens before moisture causes further deterioration can also help avoid more extensive repairs to the complete lamp assembly.
• For classic Porsche owners, retaining the original appearance of exterior lighting components is an important part of preserving the vehicle's authenticity.
• The replacement glass helps restore the factory-style finish of the rear number plate lamp, making it particularly suitable for detailed Porsche 356 restoration projects.
• Unlike replacing the complete lighting assembly, renewing the damaged glass allows the existing housing and other serviceable components to be retained.
• The OE MATCH License / Number Plate Light Glass 64463161105/1 provides an OE-style replacement solution designed to restore effective number plate illumination, protect the lamp assembly and preserve the authentic appearance of the classic Porsche 356.
