A depressible, self-contained, solar-powered, pavement embedded marker capable of withstanding the impact of a snowplow blade or a vehicle tire by retracting below the surface of the pavement while providing effective delineation of traffic lanes. The pavement marker has a housing, a core assembly mounted in the housing, a light assembly mounted to the core assembly, and a plate disposed at the top of the core assembly to protect the core assembly and to deflect the core assembly downward into the housing in response to forces applied to the plate. The pavement marker is disposed within a cavity of the pavement of a highway or roadway. A resilient, elastic, compressible, liquid-impervious mass is disposed between the core assembly and the housing filling entirely the space therebetween to provide a seal during the movement of the core assembly relative to the housing. The resilient mass is also disposed between the housing and the walls of the cavity in the pavement to provide added resilience to the marker. |
