ABSTRACT The outlay for producing an indicator device for arbitrary messages, in particular for changes of traffic conditions, which may be composed of at least one fixed indicator section and an arbitrarily selectable section, is reduced and control is simplified in accordance with the invention in that separate bundles of optical fibers which can be illuminated are provided for each non-changeable indicator section, the free ends of which are distributed in an indicator board in accordance with the associated non-changeable indicator section, that the arbitrarily selectable indicator section can be displayed by means of a matrix field of indicator elements, where each indicator element has an illuminable optical fiber with an individual switching device for opening or closing the associated light path, and that the selected, non-changeable indicator section and the selectable indicator section displayed in the matrix field are displayed together.
