The present invention refers to an indirect vision device for vehicles integrating a lighting unit, like light indicators or light decorative elements, preferably for vehicles. The lighting device (1) comprises: a light source (2), a light guide (5) for guiding light emitted by the light source (2). The light guide (5) comprises a light guide material and scattering particles (10) admixed therein, and the refractive index of the scattering particles (10) is different than the refractive index of the light guide matrix material, such that light guided by the light guide (5), can be scattered by the scattering particles (10) out of the light guide (5). The invention provides an indirect vision device with enhanced homogeneous luminance and increased luminance.
