<p>A reflective road stud comprises a cylindrical reflector 16 supported by a resilient element 14 mounted in a cylindrical casing 10 together with an annular wiper means 24 which contacts the domed surface 18 of the reflector when the latter is displaced relative to the casing against the resilient element. The reflector is particularly useful at cross-roads or intersections because it is equally effective irrespective of the angle of approach. <IMAGE></p> |
