The left (OE ref no 99663104502) or Right (OE ref no 99663104602) Headlight Lower Covers are replacement lighting trim/insert panels that fit the lower portion of the front headlight assembly on early Porsche 911 (996) and Porsche Boxster (986) models without headlight washers. These parts replicate the original insert covers used around the headlamp/indicator area, providing the correct appearance and fit.
The headlight lower cover panels finish off the headlamp assembly visually while protecting indicator and corner areas from road debris and moisture. By restoring the correct headlight trim appearance, these inserts help maintain consistent styling and proper optical contrast around the headlight area.
Installed directly beneath the main headlight lens, these covers support the indicator/side marker position and provide a finished border for the headlamp housing. Their profile helps ensure proper light dispersion around the front corner of the vehicle and maintains the intended aesthetics of the original Porsche design.
The headlight lower cover can become faded, cracked, discoloured, or damaged over time due to road debris, UV exposure, and everyday wear. A worn or broken cover not only detracts from the classic Porsche look but can expose vulnerable lighting components to contaminants. Replacing restores proper styling, protects the headlamp edge and indicator area, and helps preserve resale value and originality.
When to replace:
• Lens/cover is cracked, chipped, or broken
• Colour has faded or turned dull
• Signs of moisture ingress behind the cover
• During headlight or front bumper service
• Exterior restoration or detail work

Porsche Right Hand Drive (RHD) Headlamps | Precision Lighting for UK & Commonwealth Roads
Right-hand drive (RHD) headlamps are designed to project light beams specifically for vehicles driven on the left-hand side of the road, ensuring clear visibility without dazzling oncoming traffic. These precision lighting assemblies are essential for maintaining safety, legality, and optimal performance when driving your Porsche in the UK, Japan, Australia, and other RHD regions.
At Design911, we offer a comprehensive range of premium RHD headlamps for both classic and modern models — including halogen, xenon (HID), and LED units. Each headlamp is engineered for perfect fitment, optimal beam alignment, and exceptional clarity. Whether you’re restoring a 911, upgrading a Cayman, or replacing a worn Boxster light unit, our RHD headlamps deliver Porsche-grade performance, safety, and style.
What Do Right Hand Drive Headlamps Do?
RHD headlamps ensure proper light projection on left-hand side driving roads, providing safety, visibility, and compliance with regional standards.
Core Functions:
- Direct the light beam downwards and towards the roadside verge.
- Prevent glare and dazzle to oncoming drivers.
- Deliver clear, balanced illumination for night and low-light driving.
- Maintain compliance with UK and international lighting regulations.
- Enhance Porsche’s distinctive styling with precision optics and design.
Properly functioning RHD headlamps are essential for safety and to meet roadworthiness standards.
Why Do RHD Headlamps Fail or Degrade?
Even with advanced engineering, headlamps face constant exposure to environmental stress and vibration, which can lead to wear and performance loss.
Common Causes of Failure Include:
- Lens yellowing or fogging due to UV exposure.
- Cracks or damage from stones and debris.
- Moisture ingress causing condensation and corrosion.
- Burnt-out bulbs or LED module failure.
- Reflector fading or peeling reducing light projection.
- Damaged adjusters or misalignment over time.
When RHD headlamps become dull, cracked, or misaligned, visibility drops and MOT failure becomes likely — making replacement essential.
Why Replace or Upgrade Your Porsche RHD Headlamps?
Replacing or upgrading your Porsche’s RHD headlamps restores optimal beam focus and night-time visibility while enhancing the vehicle’s aesthetics.
Key Benefits:
- Restores full brightness and road safety compliance.
- Improves visibility and clarity for night or foggy driving.
