What Does the Additional High Beam Headlight Lens Do?

The additional high beam lens is an important part of the auxiliary lighting system.

Its primary functions include:

• Protecting the headlight reflector and bulb from water, dirt and road debris.
• Maintaining the correct high beam light pattern.
• Maximising light output for improved night-time visibility.
• Helping seal the lamp assembly against moisture.
• Completing the factory appearance of the additional driving light.

A clear, undamaged lens ensures optimum lighting performance while protecting the internal components from damage.

Why Does the High Beam Lens Need Replacing?

Located at the front of the vehicle, the lens is exposed to constant impacts and environmental conditions.

Common causes of deterioration include:

• Stone chips from road debris.
• Cracks caused by impact damage.
• Surface scratching and pitting.
• Clouding or dulling from UV exposure.
• Moisture ingress through damaged glass.
• General ageing after decades of service.

A damaged lens can reduce light output, alter the beam pattern and allow water to enter the lamp housing, potentially damaging the reflector and bulb.

When Should It Be Replaced?

Replacement is recommended when:

• The lens is cracked or chipped.
• The glass has become cloudy or heavily scratched.
• Water or condensation is visible inside the lamp.
• High beam performance has noticeably deteriorated.
• Restoring the auxiliary lighting system.
• Completing a concours or factory-correct restoration.

Replacing the lens restores both the effectiveness of the additional high beam lamp and the original appearance of your Porsche.
