<p>The invention relates to signalling means particularly for roads. The advantages provided by the presence of reflective or illuminated road studs has long been known. Conventional road studs stand proud of the road surface to enable the reflector or the illuminatable means to be seen, and are prone to damage by passing traffic, and particularly by the blades of snow ploughs. The object of the invention is to reduce substantially, or eliminate this disadvantage, an objective met by a construction comprising a socket, a domed lens mounted on the socket and reflective and/or illuminatable means mounted in the socket, the domed lens being of a material able to refract reflected light, or light from the illuminatable means, to allow it to be seen by drivers of oncoming vehicles.</p> |
