Lighting and/or signalling device comprising - a container body having a plurality of containment seats each containment seat housing at least one light source electrically connected to electrical connection means to power the same, and suitable for emitting a beam of light to propagate to the outside of the lighting and/or signalling device, - a lenticular body, positioned so as to close the plurality of containment seats and suitable to receive the beam of light produced by each light source and to propagate it towards the outside of the lighting and/or signalling device, at least in a longitudinal direction (X-X) of propagation of the beam of light, - wherein the lenticular body, at each containment seat comprises a first lighting portion, used to diffuse a beam of light of a predefined colour, delimited by a first optic filter, having a first colour different from said predefined colour, - each light source being positioned inside the containment seat in a position rearward of the lenticular body, in a longitudinal direction (X-X) of propagation of the beam of light, - each light source facing a light guide which comprises a light input wall which receives the beam of light produced by the light source, propagates it along a light guide body and emits it from a light output wall, facing the lenticular body so that the beam of light crosses the lenticular body, - wherein between each light source and the light input wall a second optic filter is positioned, having a second colour different from the first colour of the first optic filter so that the beam of light produced by each light source and filtered by the second and by the first optic filter (52, 28) in succession comes out of the lenticular body having said predefined colour, wherein the first optic filters of adjacent portions of lenticular body are the same colour so as to prove substantially indistinguishable when the respective light sources are deactivated, characterized in that the at least one light source includes a power supply and support strip and the second optic filter is associated to the power supply and support strip of the light source, so as to position itself between the light source and the light input wall of the light guide. - a container body having a plurality of containment seats each containment seat housing at least one light source electrically connected to electrical connection means to power the same, and suitable for emitting a beam of light to propagate to the outside of the lighting and/or signalling device, - a lenticular body, positioned so as to close the plurality of containment seats and suitable to receive the beam of light produced by each light source and to propagate it towards the outside of the lighting and/or signalling device, at least in a longitudinal direction (X-X) of propagation of the beam of light, - wherein the lenticular body, at each containment seat comprises a first lighting portion, used to diffuse a beam of light of a predefined colour, delimited by a first optic filter, having a first colour different from said predefined colour, - each light source being positioned inside the containment seat in a position rearward of the lenticular body, in a longitudinal direction (X-X) of propagation of the beam of light, - each light source facing a light guide which comprises a light input wall which receives the beam of light produced by the light source, propagates it along a light guide body and emits it from a light output wall, facing the lenticular body so that the beam of light crosses the lenticular body, - wherein between each light source and the light input wall a second optic filter is positioned, having a second colour different from the first colour of the first optic filter so that the beam of light produced by each light source and filtered by the second and by the first optic filter (52, 28) in succession comes out of the lenticular body having said predefined colour,
