Signal lamp for a vehicle configured to create an illumination pattern. It includes an illuminant configured to emit parallel light, a first optical element configured to receive light from the illuminant, and a second optical element configured to receive light from the first optical element. The light entry surface of the first optical element has a plurality of concave cylinder diverging lenses (CDLs), wherein the light exit surface of the second optical element has a plurality of convex cylinder converging lenses (CCLs). The CDLs are oriented on the light entry surface such that their cylinder axes are rotated by a first angle around a main axis, wherein the CCLs are oriented on the light exit surface such that their cylinder axes are rotated by a second angle around the main axis. The first and second angles are such that in a frontal view towards the light exit surface of the second optical element the CDLs overlap with the CCLs in order to form a lattice.
