A floor mat system that includes a mat having a decoratively shaped first portion that allows light to transmit therethrough and is surrounded by a second portion that does not allow light to transmit therethrough. A light source is positioned beneath at least the first portion of the mat. When activated, the light source shines through the first portion and thereby illuminates and draws attention to the decorative image. The light source is coated in a polycarbonate resin film to protect and strengthen the same against damage as people walk over the mat. A non-transparent coating may be applied to selective regions of the protective film to create the same decorative transparent image therein and to thereby allow light to only be emitted from a particular region of the light source. The mat may be made from a flow-through material, a non-flow-through material with a gripping upper surface and wells; or a combination of flow-through and non-flow-through material. The mat also includes a transformer housing and channels to protect a transformer and electrical wiring from being damaged as people walk over the mat.
