A pavement marker including a body (1), at least one hermetic chamber (14) in the body, a reflector panel (6,7) positioned in the side of the body (1) for each chamber and sufficiently transparent to allow the passage of light therethrough and form a window in the body (1) into the hermetic chamber

A pavement marker including a body (1), at least one hermetic chamber (14) in the body, a reflector panel (6,7) positioned in the side of the body (1) for each chamber and sufficiently transparent to allow the passage of light therethrough and form a window in the body (1) into the hermetic chamber (14), a substantially smooth external face on the reflector panel (6,7) which lies at an acute angle to a base surface of the body (1) and reflective prismatic projections (8) on an inner face of said reflector panel (6,7) with the projections spaced from a back face (11) of said chamber (14).

A pavement marker, comprising: a base surface; a saucer-like shell body made of plastic material and having an integral light-transparent wall zone with a substantially flat outer surface of said light-transparent wall zone lying in a plane at an acute angle to said base surface; shoulder means bordering an inner face of said light-transparent wall zone; ribs upstanding from said inner face of said light-transparent wall zone for dividing said inner face of said light-transparent wall zone into separated areas and intersecting with said shoulder means, said ribs having upper edges; a continuous bonding path comprising said shoulder means and said upper edges of said ribs; uncoated reflective prismatic projections upstanding from a surface of said separated areas and terminating at an elevation below the elevation of said bonding path; a backing plate sealing bonded to said continuous bonding path for providing hermetically sealed chambers with each containing said prismatic projections spaced from said backing plate; and, an infill material bearing against said backing plate and filling said saucer-like shell and forming said base surface for said pavement marker.
