摘要： A lighting and/or signalling device includes a container body having containment seats housing at least one light source for emitting light. A lenticular body closes the containment seats and is suitable to receive the beam of light and propagate it. A first lighting portion diffuses light of a predefined color, delimited by a first optic filter, having a first color different from the predefined color. Each light source is inside the containment seat and receives the beam of light, propagates it along a light guide body and emits it across the lenticular body. A second optic filter has a second color. The light produced by each light source and filtered by the second and by the first optic filter comes out of the lenticular body having the predefined color. The first optic filters are the same color so as to prove substantially indistinguishable when the respective light sources are deactivated.
