Vehicle exterior system with light module

A lighted exterior mirror system suitable for use in a vehicle includes a lighted exterior rearview mirror assembly having a light module, which includes a planar circuit board and a light guiding element. The light module includes a plurality of illumination sources disposed on a mounting side of the circuit board and operable to emit light. When the illumination sources are actuated, light emitted by each of the illumination sources is emitted in a direction normal to the mounting side of the planar circuit board. The light guiding element is configured so that light emitted by the illumination sources is redirected by the light guiding element so that light emanates from the light guiding element in a direction parallel to the mounting side of the planar circuit board and parallel to the road surface.
