Retroreflective stud having constant omnidirectional effect, which is self-cleaning and can be renewed on the road without exchanging the reflector, characterised by the possibility of various types of retroreflective elements (1) being adapted to a piece (2) of adaptable external geometry, which is mounted concentrically to a sealed protecting body which is very resistant and consists of a base (4) surmounted by an optical means (11), these pieces being generated by revolution. <IMAGE> |
