Реферат: A light-guide lighting or signalling device, for example for lights of motor vehicles, comprises a light guide (2) and at least one light source (8, 9) provided in a position adjacent to a surface of the light guide. The light guide has roughened surface portions (4, 5) to enable extraction outwards of the light that propagates within the light guide. Associated to a surface (4) of the guide (2) is a distribution (11) of mirrors (12), which reflects the light extracted so that it is redirected through the light guide and made to emerge therefrom.
