Purpose and vehicle placement

The LED projector is designed for installation in the front doors, on the left or right side, in place of the factory lamps in the lower part of the door panel. This placement allows for effective illumination of the vehicle's entry zone and displays the logo directly on the surface next to the car. This solution improves visibility when entering and exiting the vehicle, while also serving as a consistent stylistic element with other Audi visual accessories.

Construction and LED technology

The lamp uses an LED light source, which is characterized by a stable luminous flux and low energy consumption. The integrated optical module is responsible for the precise reproduction of the logo, without blurring the edges and while maintaining proper contrast. The projector's construction is prepared for operation in conditions typical for car doors, taking into account temperature changes and increased humidity in this area.

Decorative and functional role

When the door is opened, the projector activates along with the interior lighting, casting a clear Audi S4 B9 logo onto the ground. This effect:

• emphasizes the sporty character of the vehicle and its belonging to the S line,
• facilitates orientation when entering the vehicle after dark,
• visually enriches the cabin entry zone.

Thanks to this, the element plays both a decorative and practical role, fitting into the concept of subtle yet noticeable optical tuning.

Product characteristics and installation

The LED projector belongs to the Trims, decorative moldings and decorations group, which means it is treated as a body and interior finishing element, not a mechanical part. The product is used, which in practice means it comes from disassembly and may show signs of wear typical for this type of component, while maintaining functionality suitable for further use. Installation takes place in the place of the factory door lamp, using the existing electrical installation socket, which limits the scope of work to workshop activities without the need to interfere with the vehicle's wiring harness.

Application in Audi vehicles

The discussed projector is an original Audi component, intended primarily for models from the S4 B9 family, in which factory door lighting with a logo is used. This ensures a consistent fit of the housing shape to the door panel and compatibility with the factory lighting system. Choosing an original component allows you to maintain a uniform standard of finish and avoid problems typical of low-quality replacements.

If you are planning a comprehensive repair or upgrade of the threshold area in your Audi and need other elements from the same group, such as covers, overlays, or additional moldings, check the available parts in the Audi trims, decorative moldings and decorations category.
