A lighting device to be installed on an instrument panel in a vehicle cabin. The lighting device is configured to emit light in a first direction toward a seat in the vehicle cabin so as to be directly visually perceived by an occupant sitting in the seat and to emit light in a second direction toward an interior of the vehicle cabin so as to be reflected by the interior and then visually perceived by the occupant.

The vehicle interior component includes a front surface side space and a slit. Alight emitting part, which is disposed on a vehicle interior outer side with respect to at least one of the vehicle interior outer side end of the panel lower portion of the upper panel and the vehicle interior outer side end of the panel upper portion of the lower panel and emits light emitted obliquely upward toward an inside of a vehicle interior through the slit, is provided.

A steering wheel assembly having a steering wheel base plate, a safety airbag and a cover and a housing, wherein the cover and the housing define a space for accommodating an airbag and a light-emitting mark. The light-emitting mark includes an electronic control element, a mark portion, and a flexible circuit board. The electronic control element is configured to be based on a rigid printed circuit board. The flexible circuit board is configured to have a first end connected to the electronic control element and a second end connected to the mark portion so that the electronic control element controls light emission of the mark portion by means of the flexible circuit board. The electronic control element is arranged in a first position in the steering wheel assembly. The mark portion is arranged in a second position in the steering wheel assembly. The second position is positioned at the cover.

Various implementations of an illumination system include a light guide, a housing having a ceiling and defining a window, and a base coupled to the housing. The light guide is supported between the base and the ceiling. At least one light source is disposed adjacent a first end of the light guide. The light guide transmits the light from the light source through at least a portion of the outer surface of the light guide and the window. One or more tabs extending from the base each define at least one opening, and the at least one opening defined by each tab is alignable with an opening in a spoke portion of a frame. The openings receive a fastener to couple the base to the spoke portion. The housing may be integrally formed with a trim cover coupled to the frame.
