The module (1000) has an actual light source and a system (1001) for concentrating the light rays from the source on the end of a light duct (1100) made up of a series of adjacent transparent plates (1110, 1120, 1130) lying in line with the duct's axis (X - X). The plates, which are joined together at intervals by 3 - 5 mm spots of adhesive, have at least one oblique reflective face (1111, 1121) which forms a virtual light source and is positioned so to co-operate optically with dioptric elements (1111a, 1121a). The transparent plates are of glass and are of different lengths, with the upper shortest one attached by a single spot of adhesive to the one below it, and with intermediate plates joined by two spots of adhesive at each end.
