Abstract

A reflective road stud comprises a resilient shell having a recess in which a reflective device is mounted. In order that an block insert having an array of reflective elements may be used, a flange is formed integrally with the shell behind the recess, and the block insert is bonded to the flange. In order to provide for a self-wiping action, slots are formed between the shell and the sides of the flange, and a shearable connection is provided between the shell and the bottom of the flange. Upon shearing or cutting of the connection, a wiper lip is formed which wipes the reflective elements, upon depression of the shell by a vehicle tire. In an alternative embodiment the block insert is mounted on a flap behind the recess.
