A vehicular illumination system structured as an array of optical trains in each of which the element of a light-concentrating optical sub-system and the element of the projection optical sub-system are uniquely spatially mapped one into another to ensure that light from a given optical source of the employed arrays of optical sources necessarily interacts both with a dedicated, spatially-distinct light concentrator of the corresponding optical train and with a dedicated, spatially-distinct projection optical component while not interacting with either the light concentrator or the projection optical component of the neighboring optical train. Embodiments ensure freedom of change of the overall shape of the system while, in operation, forming light distribution in pre-determined illumination plane that is substantially devoid of visually-perceived color aberrations.
