Abstract
An illumination module configured for mounting at a vehicle includes at least one illumination source and an optic. The optic is a three dimensional single formed optic that is formed such that, when the illumination source is operated and when the illumination module is disposed at a side of a vehicle, the optic provides projection of an icon, a logo and/or indicia at a ground region at or near the side of the vehicle. The optic includes one of (a) a lens optic configured such that light emitted by the illumination source, when activated, passes through the lens optic to provide projection of the icon, the logo and/or indicia, and (b) a reflector optic configured such that light emitted by the illumination source, when activated, reflects off the reflector optic to provide the selected projection of the icon, the logo and/or indicia.
