<p>The signalling light (30) has first (31) and second (32) alternate zones, throughout its thickness, of two differently stained transparent materials . The first zone has, on the interior side of the light, surfaces (31a) allowing passage of rays originating from the light source to the outside. The second zone has, on the interior side of the light, surfaces (32a) ensuring a reflection of the greater part of the incident rays from the light source. The surfaces of the first and second zones are smooth and flush. The internal surfaces of the second zone are formed in part from trihedral reflectors not ensuring retroflex reflection. There is a clear faded red reversing light with a red reflector. The lamp is clear, the first zones being clear and the second zones are red. <IMAGE></p> |
