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.

Focus
and direct light accurately
Improve
night-time visibility
Maximise
headlight performance
Protect
bulbs and reflectors
Prevent
water and dirt ingress

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

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

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