12 A reflective pavement marker includes a hollow, hermetically sealed base having a flexible top wall defining at least one downward recess. The base is installed in an opening in a roadway, with the top wall flush with the surface. In each recess there is provided a reflector unit which includes an upper portion projecting upwardly above the top of the base, and converging upwardly so that impact from a moving object will cause a camming action that urges the reflector unit downwardly. The reflector unit includes at least one light-reflective compo nent supported and protected by the upper portion. |
