Abstract

The invention relates to a variable message optic fibre signalling device particularly designed for traffic signs, which comprises a plurality of optic fibres (1), arranged between a light source (3) and a first intermediate panel (11), which is arranged in a facing and spaced relationship with respect to a second intermediate panel (12), therefrom a second plurali­ ty of optic fibres (13) extend, which are coupled to an outer panel (15).
Between the intermediate panel there is arranged a shutter element (20), of variable position, and adapted to modify a message which can be dis­ played on the outer panel.
