The present invention relates to indicator panels and their method of production. The indicator panel is characterised essentially by the fact that it consists of a mouldable basic material 1 able at least partially to absorb visible light, and of particles 2 randomly embedded in the said base material, the particles being able to emit visible light. Applications, especially, to the signposting indicator panels along the road, and for paving slabs. <IMAGE>
