The **interior lighting** has the specific function of **illuminating the vehicle's cabin**. This means its purpose is to provide light within the space where the driver and passengers are located, allowing for a clear view of the car's interior, especially in low-light conditions or at night.

Unlike other vehicle lights, such as position lights or high beams, which are designed to illuminate the exterior of the vehicle or the road, the interior lighting focuses exclusively on the inside of the vehicle. It is not intended to illuminate the hood or the trunk, as those areas may have their own specific lights for those purposes.
