Light module (2A, 2B, 2C, 2D, 2E) for lighting and/or signaling for a motor vehicle, comprising: - a first light guide extending between a proximal end and a distal end, the first light guide being delimited by two big faces which are parallel or essentially parallel to each other, a first light source being arranged in front of the proximal end of the first light guide, so as to allow the propagation of a light beam between both big faces and in a direction of propagation parallel or essentially parallel to the big faces, the first light guide comprising scattering elements suitable for deviating the light that propagates inside the light guide towards the big faces along the direction of propagation, the big faces of the light guide being twisted along the direction of propagation, and - a second light guide extending between a proximal end and a distal end, the second light guide being delimited by two big faces which are parallel or essentially parallel to each other, a third light source being arranged in front of the proximal end of the second light guide, so as to allow the propagation of a light beam between both big faces and in a direction of propagation parallel or essentially parallel to the big faces, the second light guide comprising scattering elements suitable for deviating the light that propagates inside the second light guide towards the big faces, a big front face of the second light guide facing a big rear face of the first light guide, characterized in that: i) the scattering elements form a light pattern when the first light source lights the first light guide, and in that: ii) the scattering elements of the second light guide are arranged in the second light guide so as to form, when they are lighted, a homogeneous or essentially homogeneous shimmering background for the first light guide; and/or iii) the light module comprises an optical reflector arranged in front of a big rear face of the second light guide. - a first light guide extending between a proximal end and a distal end, the first light guide being delimited by two big faces which are parallel or essentially parallel to each other, a first light source being arranged in front of the proximal end of the first light guide, so as to allow the propagation of a light beam between both big faces and in a direction of propagation parallel or essentially parallel to the big faces, the first light guide comprising scattering elements suitable for deviating the light that propagates inside the light guide towards the big faces along the direction of propagation, the big faces of the light guide being twisted along the direction of propagation, and - a second light guide extending between a proximal end and a distal end, the second light guide being delimited by two big faces which are parallel or essentially parallel to each other, a third light source being arranged in front of the proximal end of the second light guide, so as to allow the propagation of a light beam between both big faces and in a direction of propagation parallel or essentially parallel to the big faces, the second light guide comprising scattering elements suitable for deviating the light that propagates inside the second light guide towards the big faces, a big front face of the second light guide facing a big rear face of the first light guide, i) the scattering elements form a light pattern when the first light source lights the first light guide, and in that: ii) the scattering elements of the second light guide are arranged in the second light guide so as to form, when they are lighted, a homogeneous or essentially homogeneous shimmering background for the first light guide; and/or iii) the light module comprises an optical reflector arranged in front of a big rear face of the second light guide. ii) the scattering elements of the second light guide are arranged in the second light guide so as to form, when they are lighted, a homogeneous or essentially homogeneous shimmering background for the first light guide; and/or iii) the light module comprises an optical reflector arranged in front of a big rear face of the second light guide.
