The H4 lens features a specific optical pattern designed for right-hand drive vehicles, ensuring the correct beam distribution for UK and other RHD markets. A clear, undamaged headlamp lens is essential for maintaining optimum visibility, especially during night driving and poor weather conditions.

Over time, headlamp lenses can become scratched, chipped, cracked or cloudy due to age, UV exposure and road debris. Replacing a worn lens helps restore headlight performance, improve safety and maintain the original appearance of your Porsche.

What Does a Headlamp Lens Do?

The headlamp lens forms the front protective cover of the headlight assembly and helps control the distribution of light produced by the bulb and reflector.

A correctly functioning headlamp lens helps:

Focus and direct light accurately Improve night-time visibility Maximise headlight performance Protect bulbs and reflectors Prevent water and dirt ingress Maintain legal beam patterns Preserve original vehicle appearance

For right-hand drive vehicles, the lens design ensures the beam pattern illuminates the road correctly without causing glare to oncoming traffic.

Symptoms of Headlamp Lens Wear or Failure

Headlamp lenses are constantly exposed to environmental conditions and road hazards, making them vulnerable to deterioration over time.

Common signs that a headlamp lens requires replacement include:

Cloudy or hazy lens surface Reduced headlight brightness Scratches or stone chips Cracks in the lens Moisture or condensation inside the headlamp Yellowing or discolouration Distorted beam pattern Poor night-time visibility MOT or roadworthiness concerns

A damaged lens can significantly reduce lighting performance and compromise driving safety.

Why Headlamp Lens Replacement Matters

Replacing a worn or damaged headlamp lens helps restore both safety and appearance while protecting the internal components of the headlight assembly.

Benefits include:

Improved light output Enhanced night-time visibility Correct beam pattern performance Better road safety Protection against moisture ingress Reduced risk of reflector damage Improved vehicle appearance Enhanced originality for restoration projects

For Porsche 911 and Porsche 964 owners, maintaining clear and effective headlamps is an important part of preserving both vehicle value and driving confidence.

Features & Benefits

• H4 specification
• Right-Hand Drive (RHD) beam pattern
• Restores headlight clarity and performance
• Improves visibility and road safety
• Protects internal headlamp components
• Ideal for restoration, maintenance and refurbishment projects

Headlamp rim, 1 hole, metal carbon look.
The OE Match headlamp outer bezel in metal carbon look is a replacement trim ring designed for Porsche 911 (1975–1989) and Porsche 964 (1989–1994) models. This bezel surrounds the headlamp unit and secures the headlight assembly to the front wing while providing a distinctive carbon-look metallic finish that gives a sportier appearance to the classic Porsche front end.

Manufactured to match the original Porsche design and mounting configuration, it provides a direct replacement for worn, corroded or damaged headlamp trim.

The headlamp bezel (also called a headlamp trim ring) is the outer frame that holds the headlight assembly against the vehicle’s front wing. The OE Match version replicates the factory dimensions and mounting design used on air-cooled Porsche models to ensure proper fitment and alignment.

This version features a metal carbon-look finish, offering a subtle performance-inspired styling upgrade while retaining the classic shape of the original headlamp ring. The bezel includes the correct mounting hole for the retaining screw and can be installed on either the left or right side of the vehicle.

The bezel secures the headlamp assembly to the body and provides the visible trim ring that blends the headlight into the vehicle’s bodywork. It ensures the headlamp is held firmly in place while protecting the headlight housing from vibration and minor debris.

Replacing damaged bezels restores proper headlamp alignment and enhances the overall appearance of the vehicle’s front lighting system.

Headlamp bezels are exposed to road debris, weather and corrosion. Over time they can become scratched, bent or rusted, which affects both the appearance and the stability of the headlamp assembly. Installing a new OE Match bezel restores proper fitment and helps maintain the clean, finished look of the classic Porsche front end.

Replace the headlamp bezel if you notice:
•  Corrosion or pitting on the trim ring
•  Bent or damaged headlamp surround
•  Loose headlamp assembly
•  During front-end restoration or cosmetic upgrades
