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 component supported and protected by the upper portion.

[ I claim:] [4.] A reflective pavement marker comprising:a hollow, hermetically sealed base having a flexible top wall defining a plurality of downward recesses, the base being adapted to be installed in an opening in a road surface such that the top wall lies at or below the road surface,and, for each said recess, a reflector unit having a lower portion snugly received in the respective recess and an upper portion projecting upwardly above the top wall of the base, said upper portion converging upwardly such that impact from a horizontally moving object will cause a camming action that urges the reflector unit downwardly;at least one light-reflecting component supported and protected by each said upper portion;the recesses being disposed such that a plow blade passing over the marker impacts each reflector unit at a different time, thus averaging out the total impact.
