A light element for a bodywork component is provided. The light element includes at least one light source and a light guide, where the light guide forms a profile of an open cross-section, comprising: a first element made of injection-molded transparent polycarbonate, defining, along substantially the entire length of the profile, a zone (ZT) that is transparent to the light emitted by the light source; at least one second element made of injection-molded black polycarbonate, defining, along substantially the entire length of the profile, a zone (ZO) that is opaque to the light emitted by the light source; the light source emitting light from inside the profile toward the transparent and opaque zones.
