* Compatible with pre-1973 cars with H4 Headlamps, we also offer the original Bosch H1 Headlamp glass
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 appearanceFor 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 concernsA damaged lens can significantly reduce lighting performance and compromise driving safety.

Benefits include:
- Improved light output
- Enhanced night-time visibility
- Correct beam pattern performance
