Purpose and compatibility

The presented xenon gas discharge lamp is designed for factory-fitted xenon headlights used in, among others, the Audi S3, Audi A3 8V, and Volkswagen Sharan 7N. As a component from the Lamps and LED lights group, it works with the vehicle's original ballasts and electrical installation, which reduces the risk of lighting system errors and onboard diagnostic issues.

Gas discharge technology and performance parameters

The xenon gas discharge lamp generates intense, uniform light that illuminates road shoulders and further sections of the road better than classic halogen bulbs. Stable color temperature and high luminance contribute to driving comfort at night, reducing driver eye fatigue. The use of original gas discharge technology allows for maintaining the correct light distribution in the headlight, which is important for both safety and compliance with vehicle lighting regulations.

Original origin and condition of the component

The bulb comes from the Volkswagen OE line, which means it maintains factory standards of quality, geometry, and compatibility with headlights used in the VAG group. The item is offered as used, making it an economical solution while maintaining the manufacturer's original specifications. This is a beneficial option for post-accident repairs, replacing a single bulb, or restoring full functionality to a xenon system.

Practical application and installation

The xenon gas discharge lamp is intended for installation in place of the factory bulb in a xenon headlight. When correctly matched to the vehicle model and headlight type, the installation is plug-and-play, with no need for electrical modifications. In practice, this means:

• maintaining proper cooperation with the ballast and electrical installation,
• correct operation of burnt-out bulb control systems,
• maintaining the proper light beam geometry after headlight adjustment.

Thanks to this, the replacement is quick, and the risk of fitment issues is minimal, provided the bulb is used in the models intended for it.

Safety and lighting selection

Efficient xenon lighting has a direct impact on driving safety, especially on unlit roads. Proper selection of the bulb for a specific headlight model helps avoid blinding other road users and ensures uniform road illumination.
