<p>A retro reflective road/pavement marking stud has a body 1 containing a recess or recesses 2 into which the retro reflective component 3 locates. When located, the retro reflective exposed surface is still recessed within the surrounding stud body. When trafficked by a vehicular tyre the contact is restricted substantially to the stud body and not the recess or retro reflective component contained therein. <IMAGE></p> |
