Bulbs H7 XENON PLUS (Ring 848) 30% Brighter

The Ring Xenon Plus premium performance halogen bulb makes driving at night brighter, easier and safer…this is because Ring Xenon Plus headlamp bulbs are up to 30% brighter than conventional bulbs - not only making it easier for you to see where you're going but also making sure other drivers see you coming without being blinded by your lights.
The secret of the high performance bulb is that the filament is precision designed to focus as much light as possible in the key areas, to enhance visibility. In addition, the bulb should outperform standard bulbs due to a mixture of gases which prevent the filament from burning too quickly. And they don't need any extra power, which means that upgrading your headlights is simply a matter of changing the bulbs with no need to make alterations to switches or cables. As the bulbs have a low UV output, they are suitable for plastic headlamps, lenses or reflectors. Ring Xenon Plus bulbs must be fitted in pairs.

About Main/Full Beam Bulbs

Porsche Main / Full Beam Bulbs | High-Performance Lighting for Maximum Visibility

Main beam (or full beam) bulbs are designed to deliver maximum illumination when driving at night or in poorly lit conditions. Unlike dipped beams, which provide a controlled, short-range spread of light, main beam bulbs project a powerful, far-reaching beam to illuminate the entire road ahead. This ensures exceptional visibility during open-road and high-speed driving.

At Design911, we offer a complete range of high-performance main and full beam bulbs, including halogen, xenon (HID), and advanced LED options. Each bulb is engineered for perfect fitment, consistent brightness, and superior beam precision. Whether you’re restoring a classic Porsche or upgrading a modern model, our bulbs deliver exceptional clarity, performance, and reliability in all conditions.

What Do Main / Full Beam Bulbs Do?

Main beam bulbs play a critical role in road safety and performance driving by providing long-range illumination when needed.

Core Functions:

  • Project high-intensity light for maximum distance visibility.
  • Improve reaction times during night or high-speed driving.
  • Enhance safety on unlit roads, rural routes, and motorways.
  • Operate as part of Porsche’s dual-beam or adaptive headlight systems.
  • Maintain the vehicle’s lighting performance and design integrity.

Properly functioning main beam bulbs are vital for safe, confident driving in low-visibility conditions.

Why Do Main / Full Beam Bulbs Fail or Degrade?

Even the highest-quality bulbs experience wear and performance loss over time due to heat, vibration, and voltage stress.

Common Causes of Failure Include:

  • Filament burnout or wear from prolonged use.
  • Vibration damage from rough roads or performance driving.
  • Lens fogging or headlamp housing corrosion.
  • Electrical connection faults or voltage spikes.
  • LED or HID module degradation over time.

When main beam bulbs dim or fail, your Porsche’s visibility and safety are compromised — making timely replacement crucial.

Why Replace or Upgrade Your Porsche Main / Full Beam Bulbs?

Replacing or upgrading your main beam bulbs restores full lighting intensity, improves visibility, and ensures optimal night-driving performance.

  • Restores full lighting strength and beam accuracy.
  • Enhances safety during night and motorway driving.
