LUMINESCENT RAISED PAVEMENT MARKER
A raised pavement marker (RPM) is sized and configured to comply with Department of Transportation requirements and includes a main body with a top side, opposite angled side faces, opposite ends and a bottom surface structured to be bonded to a road surface. A sheet substrate is coated on a top surface with multiple layers of a photoluminescent composition containing one or more rare earth materials that emits a highly visible glowing light in dark or near dark conditions for at least 6 hours when fully charged. The sheet substrate is inserted within a recessed pocket on the top side of the RPM with the photo-luminescent top surface facing up and is covered by a transparent acrylic lens that is electronically welded to the main body to provide an integral one piece sealed structure. The opposite angled side faces may be fitted with prismatic reflective lenses.
