What This Product Does
The electric fan moves air within the applicable LED headlamp assembly to assist the thermal management of the LED module and associated electronics. It is an internal headlamp component rather than a complete lamp unit.
Functions
- Circulates air inside the LED headlamp
- Supports cooling around the LED module
- Assists with management of heat from headlamp electronics
- Fits into the original Porsche headlamp arrangement
Technical Details
- Part number: 9A790746300
- Part description: Fan for headlamps
- Manufacturer: Porsche
- Quantity: two per listed vehicle application
- Porsche 718 specification: PR:602 LED headlights with PDLS Plus
- Macan specifications: PR:8EX, PR:8EY and PR:8IS LED headlights with dynamic cornering light
Symptoms of Fault
- Noise coming from inside the headlamp housing
- Cooling fan not operating when activated
- Intermittent behaviour from the LED headlamp
- Exterior-lighting or headlamp warning messages
- Stored diagnostic faults associated with the headlamp electronics or LED module
Why Replacement Matters
A defective fan may reduce the airflow intended for the LED module and electronic components. Electrical diagnosis should be completed before replacement because similar symptoms can result from damaged wiring, poor connections, moisture ingress, control-unit faults or other internal headlamp components. Genuine Porsche construction retains the factory connection and installation arrangement.
FAQs
- Is this a complete LED headlamp?
No. It is the internal cooling fan fitted to the applicable headlamp assembly. - Will a new fan resolve every headlamp warning?
No. The connectors, wiring, LED control units, moisture condition and complete headlamp assembly should also be inspected.

Porsche Headlamp Parts & Lenses | Precision Lighting Components for Safety and Style
Headlamp parts and lenses are critical to both the performance and appearance of your Porsche. Designed to focus and project light accurately, they ensure optimal road illumination and visibility while maintaining your vehicle’s iconic front-end styling. Over time, exposure to UV light, road debris, and weather can degrade headlamp lenses and components — leading to reduced brightness, clouding, or misalignment.
At Design911, we supply high-quality headlamp parts and lenses engineered for exact fitment and performance. Our selection includes replacement lenses, seals, adjusters, mounting brackets, and internal reflectors — available for both classic and modern Porsche models. Choose from standard or upgraded materials, including clear and UV-resistant polycarbonate lenses, for lasting clarity and precision lighting output.
Whether you’re restoring a vintage 911 or maintaining a modern Cayman, our Porsche lighting parts help you keep your headlights shining bright and clear.
What Do Headlamp Parts & Lenses Do?
Headlamp components work together to project, focus, and protect your lighting system for maximum road safety and visibility.
Core Functions:
- Lenses protect internal bulbs and reflectors while focusing light onto the road.
- Reflectors optimise light projection for balanced illumination.
- Seals and covers prevent moisture and dirt ingress.
- Mounting brackets and adjusters ensure perfect alignment and beam angle.
- Maintain the vehicle’s signature Porsche look with precision-matched housings.
Without functional headlamp parts, your Porsche’s visibility, safety, and design integrity can all be compromised.
Why Do Headlamp Parts and Lenses Fail or Degrade?
Even with high-end engineering, Porsche headlamp components are exposed to extreme temperatures, UV rays, and vibration, leading to gradual deterioration.
Common Causes of Failure Include:
- Lens yellowing or clouding from UV exposure.
- Cracks or chips caused by stone impacts.
- Moisture ingress due to worn seals or gaskets.
- Corrosion on reflectors or mounting hardware.
- Alignment issues caused by damaged brackets or adjusters.
- Age-related fading reducing light projection.
Aging or damaged headlamp lenses not only reduce visibility but can also fail MOT inspections and diminish your Porsche’s visual appeal.
Why Replace or Upgrade Your Headlamp Parts and Lenses?
Replacing or upgrading your Porsche’s headlamp components restores lighting performance and sharpens your vehicle’s front-end appearance.
Key Benefits:
- Restores optimal lighting performance and beam focus.
- Prevents moisture damage and electrical corrosion.
- Enhances clarity and visibility with new or upgraded lenses.
