ABSTRACT A depressible pavement marker is provided and includes a base receptacle, a piston assembly with a reflector and a resilient, compressible, water impervious mass. The base receptacle is mounted in the pavement with a portion of the piston assembly protruding above the pavement so that the reflector can be seen. The piston assembly and base are of a piston-in-cylinder arrangement with the piston assembly depressible into the base. The mass fills substantially the entire cavity formed between the inner surfaces of the piston assembly and the base. In another embodiment a self illuminating marker is provided and includes a solar cell, rechargeable battery, light source and sensor. The solar cell recharges the battery during daylight hours. The sensor energizes and de-energizes the light source in response to external indications. A further embodiments is also provided which includes a locational traffic marker having a transmitter in the piston assembly for sending a locational signal to a remote receiver such as for example a suitably equipped emergency vehicle.
