ABSTRACT:
A road surface light reflector is provided for use in complementary recesses in roads, to indicate the position of centerlines or sidelines on roads in a nocturnal environment by reflecting the light emitted by the headlights of incoming vehicles. The reflector has a discoid main body which is destined to be embedded into a road hole, so as to form a flat exposed top surface therewith, thus not protruding above the road level. The reflector main body is made of rubber, and its top portion comprises small glass particles embedded therein and covering the reflector exposed top surface, for providing a reflective exposed top surface. An alternate embodiment provides glass particles mixed throughout the whole depth of the rubber main body. The rubber main body is fixedly anchored inside its hole through the instrumentality of glue. The reflector according to the invention thus has a low production cost and can be used on roads that are likely to be snow plowed, since it does not protrude above the road level.
