Purpose and function in the vehicle

The presented roof lamp is designed for installation in the front part of the cabin, in the headliner area. It is responsible for even illumination of the driver and passenger space, making it easier to use the interior after dark, during stops, and while entering or exiting the vehicle.

The element belongs to the factory interior lighting system, ensuring it works with the vehicle's electrical installation in accordance with the manufacturer's specifications. Stable mounting and the proper shape of the lens reduce glare while providing clear, functional light.

Construction, color, and fitment

The grey housing has been selected to integrate with the typical headliner upholstery used in this model. This color scheme allows for a consistent interior look, without contrasts or visual differences between the lamp and other trim elements.

The arrangement of light points and the shape of the lens are adapted to the geometry of the front cabin area. As a result, the light beam is directed in a practical way – onto the center console, the area around the rearview mirror, and the space above the seats, which improves the ergonomics of using the vehicle.

Performance characteristics of the used element

The offered lamp is a used part, sourced from dismantling. This means it retains its factory construction and operating parameters, while offering the possibility of optimizing repair or replacement costs. Original origin facilitates proper fitment to the headliner and electrical harness, without the need for installation modifications.

Choosing a used OEM component is particularly beneficial in the case of post-accident repairs, replacement after mechanical damage, or restoring full functionality of the interior lighting after flooding or electrical failure.

Application in the interior lighting system

The roof lamp is part of the interior lighting system, responsible for:

• illuminating the driver and passenger zone in the front part of the interior,
• improving visibility of controls and storage compartments after dark,
• increasing comfort when using the vehicle during stops,
• aesthetic finishing of the headliner in the central area.

Thanks to the preservation of factory geometry and mounting points, installation is predictable, and the element forms a cohesive whole with other interior components after installation.
