The invention concerns a three-dimensional plastic product (1) with an outer surface (A), wherein at least part (B) of the outer surface (A) has retroreflective properties, wherein said three-dimensional plastic product (1) consists of a polymer chosen from thermoplastic and thermoset polymers; spherical glass beads having a median particle diameter D50 between 1 and 150 µm and a refractive index, measured at a wavelength λ of 589 nm, between 2.0 and 2.8, wherein the spherical glass beads are not hemispherically coated with a light-reflective coating; pigment flakes chosen from the group consisting of metallic pigment flakes, pearlescent pigment flakes or a combination thereof; and one or more further ingredients, wherein part (B) of the outer surface (A) with retroreflective properties comprises one or more outer retroreflective surface parts (C) wherein the spherical glass beads do not protrude from the polymer matrix. The invention further concerns processes for the production of the three-dimensional plastic product (1), uses of the three-dimensional plastic product (1) and a modified three-dimensional product (2) comprising one or more three-dimensional plastic product (1). Moreover, the invention concerns a LIDAR process of the three-dimensional plastic product (1) or of the modified three-dimensional product (2).
