    a locking mechanism operable to lock and unlock the vehicle door;

    a control of the equipped vehicle;

    a near field communication device of the equipped vehicle;

    wherein a system of the equipped vehicle authenticates a near field communication-enabled smartphone as an authorized device for communicating with said near field communication device;

    wherein said near field communication device is operable to receive signals from a near field communication-enabled smartphone when the near field communication-enabled smartphone is within a threshold distance from said near field communication device;

    wherein, responsive to the near field communication-enabled smartphone that is communicating with said near field communication device being an authorized device, said control actuates said locking mechanism to unlock the vehicle door;

    an illumination module comprising at least one illumination source;

    wherein said illumination module comprises a housing and a circuit element disposed in said housing and wherein said illumination source is established at said circuit element;

    wherein said illumination module comprises an optic element disposed in said housing and generally at said illumination source, and wherein said optic element comprises a condensing optic and a diffusing optic at least partially around said condensing optic;

    wherein said illumination module comprises a lens element disposed at said housing and comprising a projecting portion disposed generally in line with the condensing optic and an illumination portion at least partially around said projecting portion and generally in line with said diffusing optic;

    wherein, when said illumination source is activated, light emanating from said illumination source (a) passes through said diffusing optic and through said illumination portion of said lens element to provide lower intensity light at a target area, and (b) passes through said condensing optic and is intensified by said condensing optic so that light passing through said projecting portion of said lens element is projected as higher intensity light onto a portion of said target area; and

    wherein said illumination module comprises an icon element disposed along the optic path between said condensing optic and said projecting portion of said lens element, and wherein an image of an icon of said icon element is projected onto said portion of said target area.
