Vehicle illumination systems and methods
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.
