An illuminated paver comprises a body including a top part having a decorative outer surface and a separate bottom part attached to the top part. The body houses a light source to be electrically connected to an associated external power source. An inner surface of at least one of the top part and the bottom part includes a plurality of strengthening ribs extending between the top and bottom parts of the body. The strengthening ribs are configured to reflect light emitted from the light source so as to randomly disperse light passing through the decorative outer surface. An electrical cord wrap is provided on an outer surface the bottom part and includes a plurality of cord receiving recesses.

A reflective and directional water permeable paver system, which has a plurality of connection cells and is configured to support traffic, includes a marker insert. The marker insert has a continuous body wall with at least one tensioning marker rib extending from the continuous body wall. The marker insert has an insert head. The insert head diameter extending beyond the continuous body wall of the marker insert. The marker insert body diameter is substantially equal to the inner wall diameter of at least one of the connection cells.

The insert head diameter extending beyond the continuous body wall of the marker insert. The marker insert body diameter is substantially equal to the inner wall diameter of at least one of the connection cells. The insert head has a prismatic inner surface composed of an array of mirrored polygonal shapes providing at least three different reflective light vectors. The insert head has a translucent top surface covering the prismatic inner surface enabling light to penetrate to the inner surface and reflect outwardly from the insert head.

A spring tension system for a floor tile has spring loop with a base portion and a hoop portion. The base portion has two arms extending outwardly at a first angle from a center-point which together to form the hoop portion. The spring loop is formed into a first side of a first floor tile. A tapered recess is formed into a second side of a second floor tile. The tapered recess includes an opening which forms two tapered walls which extend inwardly toward a center of the second floor tile at a second angle. The second angle is smaller than the first angle. The spring loop formed into the first side of the first floor tile is received into the tapered recess formed into the second side of the second floor tile, the spring loop contacting the walls of the tapered recess to form a friction fit.

A road marker and related light based warning device are described. The road marker or device includes a thermal sensor that triggers the illumination of at least one light-emitting diode at a predetermined temperature. The temperature may be associated with ice formation. The light-emitting diode(s) may flash to alert motorists to hazardous road conditions. The road marker or device utilize simple components to increase reliability, particularly when the device is subjected to high heat such as when the device is mounted into hot tar seal. The device further includes a switching element that prevents rapid on/off cycling.
