A lighting and/or signaling device comprising a plurality of light-emitting diodes secured to a support made of plastic which has at least one three-dimensional zone in the form of a staircase made up of successive treads and risers in substantially perpendicular planes, each of the diodes being fixed respectively to one of the treads of the support, the diodes being powered by conductive metallic tracks. The conducting tracks are formed by thicknesses of metal that differ according to whether the tracks extend along the treads or along the risers, the tracks arranged on a tread being produced by a thickness of metal encrusted into the volume of the plastic support, in housings formed in the thickness of the tread. |
