The problems of the prior art are addressed by a novel tactile warning system that utilizes a separate component to add photoluminescence to the tile. In certain embodiments, the tactile warning system is a replaceable tile and a cap used to cover the fastener is made using a photoluminescent material. In other embodiments, the tactile warning system is a surface applied tile, a Cast-In-Place tile or a replaceable tile, and cavities are created on the upper surface of the tile. A photoluminescent insert is then disposed in these cavities. The photoluminescent insert may be made of plastic, aluminum or acrylic.
