An interior trim part for a bodywork component has a lighting system with a first component that generates a light signal and a second component that outputs the light signal toward the passenger compartment of the motor vehicle. The bodywork component has a moveable region (200) that can be moved with respect to a non-moveable region (300), from a stationary normal position into an open position displaced with respect to the non-moveable region (300). The first component of the light system generates, in the normal position of the moveable region (200), a light signal that is input into the second component which passes on the light signal in the manner of a lightguide.
