The present invention relates to a light module (1) for a vehicle, intended to generate a light beam along an optical axis (I), comprising: - primary light guides (2) each comprising an input diopter and an output ; - a light source (9) arranged opposite an input diopter; - a projection assembly (4) comprising a focal zone and an output member (61), said projection assembly (4) being arranged so that the light rays passing through said focal zone and reaching the output member (61) are imaged in a projection field downstream of said projection assembly; - The outputs of the guides being arranged at the focal zone. According to the invention, the light module (1) comprises at least one secondary light guide (3) distinct from the primary light guides (2), and arranged so as to deflect light rays from the light source (9) of so that they do not reach the output member (61), and / or so as to spread said light rays in said projection field.
