Purpose and Fitment

The offered light assembly is a factory Audi component, specifically designed for the B9 generation A4 sedan version, mounted on the right side of the tailgate. This ensures proper alignment with the body's contours, mounting gaps, and the light line of the second lamp segment located in the fender.

The part belongs to the Rear Lights and Brake Lights group, responsible for position and brake signaling, which directly impacts the vehicle's visibility to other road users.

Light Assembly Construction and Function

The inner tailgate light assembly works in conjunction with the outer part of the fender light, creating a uniform, continuous light signature characteristic of the Audi A4 B9. The design incorporates precise light channeling and appropriate compartment arrangement to ensure intensity and beam distribution comply with manufacturer homologation.

The original optics and the correctly shaped lens help maintain even illumination and a clear brake signal, which is crucial during sudden braking and when driving in adverse weather conditions.

Condition, Origin, and Benefits of Choosing OEM Parts

This light assembly is a used original Audi part, meaning it retains factory geometry, mounting points, and compatibility with the vehicle's electrical system. In practice, this translates to installation without modifications, proper fit with the tailgate, and no issues with seals or brackets.

Choosing a used OEM part is particularly advantageous when you want to maintain the factory appearance and lighting parameters while also managing costs compared to a new component.

Safety and Operational Aspects

A functional rear light assembly is crucial for safety – it ensures the vehicle's visibility after dark, during precipitation, and in urban traffic. Properly functioning position and brake lights help prevent rear-end collisions, and the original lamp design ensures compliance with legal requirements and the vehicle's diagnostic systems.

Using a factory part minimizes the risk of errors in the light control system, uneven illumination, or leaks that could lead to condensation inside the lens and accelerated wear of the light sources.
