The switch is part of the cabin lighting control assembly, prepared for installation in the original location in the headliner. The electrical connectors are adapted to the factory wiring harness, which facilitates installation and minimizes the risk of installation errors. The panel's construction is optimized for mechanical durability and stable operation under conditions typical for a vehicle interior.

The component belongs to the Switches, control elements and ignition switches group, which means it has been designed for repetitive operation, frequent use, and appropriate resistance to operational wear during daily vehicle use.

Benefits of using an original cabin light panel

• preservation of the manufacturer-intended cabin lighting functions.

This solution is particularly beneficial for repairs following mechanical damage to the panel, issues with switch operation, or restoring full interior functionality after previous modifications.

Characteristics of the used product
