[57] ABSTRACT
A sign comprising at least one light pipe, each light pipe made of light-transmitting material, said at least one light pipe arranged to form a predetermined message or design, each light pipe having at least two ends and carrying at least one light source proximate at least one end, each light source directed towards another end of the light pipe in the direction of extension of the light pipe, a portion of the outer surface of each light pipe being translucent permitting light to exit therefrom, the sign further carrying electrical circuit means for energizing each light source, and means for mounting the at least one light pipe to form the predetermined message or design; whereby energizing of each light source causes light to be transmitted in each light pipe, light therefrom emerging through the translucent outer surface of each light pipe for the display of the predetermined message or design.
