ABSTRACT:
A road marker is flush with and preferably slightly below the grade of the surface of the road and may be either solar operated, recharging batteries within it so that light emitting diodes which are connected to the battery source may be turned on during darker night conditions to provide illumination along the boundary lines between traveling lanes along the highway. The surface of the delineator, is profiled to provide a central depression or floor with end inclined walls, at least one of which may carry a light retro-reflective media. Light emitting elements that gain their electrical power from a battery source which itself is energized and recharged by a solar collector occupying most of the surface area of a central depression. The end walls are inclined holding the light emitting diodes, below grade and out of harm's way; the emanating light projects toward an oncoming vehicle, or in a more simplistic version, the same region has a light retro-reflective media which reflects light back to the driver of an oncoming vehicle when its lights are turned on. The marker also includes battery power management, a shock resistant sandwich structure, is networkable, may be field programmable, can distinguish artificial from natural light, and includes an integrated lens/LED assembly. The road maker is made with a peelable label over the light detector for easy removal and activation. The road maker also may be consistently installed by use of disclosed installation tabs.
