Lighting and/or signalling device (4), in particular for the automotive sector, comprising at least two separately powered and activated light sources (16',16") comprising an upstream light source (16') and a downstream light source (16") relative to a prevailing propagation direction (X-X) of respective emitted light beams, an upstream light guide (24), provided with an upstream light input portion (28), facing the upstream light source (16') so as to receive in input the light beam produced by the latter and to emit it in output through an upstream light output wall (32), a downstream light guide (36) provided with a downstream light input portion (40), facing the downstream light source (16'') so as to receive the light beam produced by the latter and emit it in output through a downstream light output wall (44), said upstream and downstream light guides (24,36) are arranged side by side in series with each other with respect to said prevailing propagation direction(X-X), so that the light beam emitted by the upstream light output wall (32) is channelled through an intermediate wall (48) of the downstream light guide (36) and by this is reflected and transmitted through the downstream light output wall (44). The upstream light guide (24) is shaped so as to transfer, by total internal reflection, the light beam emitted by the upstream light source (16') from the upstream light output wall (32) to the intermediate wall (48) of the downstream light guide (36), wherein the intermediate wall (48) comprises at least one input window (52) counter-shaped relative to a corresponding output window (56) of the upstream light output wall (32).
