• supports the maintenance of proper light distribution in the luggage compartment,
• helps secure the interior of the light fixture against contaminants from the trunk environment.

Thanks to its dedicated placement in the rear left part of the vehicle, the cover works with the factory electrical installation and the trunk upholstery construction, which facilitates service and bulb replacement.

Construction and fitment for Audi A8L D4

The discussed cover has been designed specifically for the Audi A8L D4 model, which translates into precise fitment with the trunk light housing. The component's construction takes into account:

• the bulb socket geometry used in this model,
• clips and guides matched to the factory light fixture,
• appropriate material rigidity, ensuring secure bulb retention.

Such a solution allows for installation without modifications, while maintaining the original functionality of the trunk lighting system.

Characteristics of the used component

The presented bulb cover is a used part, sourced from dismantling, which is a reasonable choice when servicing older Audi A8L D4 units. In practice, this means:
