Abstract

An automotive light (1) comprising at least one main cup-shaped body (3) having the inner surface (3i) mirror-finished so as to reflect the incident light towards its mouth (3a), and at least one light source (4) which is located next to the bottom of said main cup-shaped body (3), and is structured so as to emit light when electricity-powered; the automotive light (1) also comprising at least two additional optical filters (7, 8), which are made of transparent or semi-transparent material, and are arranged so as to be crossed in rapid sequence by the light produced by the light source (4); the two additional optical filters (7, 8) being both provided with a respective optical surface structured so as to have a decorative optical pattern which is cyclically repeated with a predetermined spatial periodicity; the shape and/or spatial periodicity of the decorative optical pattern on the first optical filter (7) being different from the shape and/or spatial periodicity of the decorative optical pattern on the second optical filter (8), and such to cause, in the light coming out from the main cup-shaped body (3), an inferometric effect with Moiré deterioration that generates a virtual decorative optical pattern different from the decorative optical patterns on the two additional optical filters. (7, 8).
