Characteristics of the used component

As a used part, the entrance lamp comes from vehicle dismantling and represents an economical alternative to a new OEM component. This type of solution is often chosen for maintenance repairs when the priority is to maintain the original specification at reasonable service costs.

In the case of interior lighting, choosing an original, used component allows you to maintain the factory color and intensity of the light, which is important for visual comfort inside the cabin.
