According to an example aspect of the present invention, there is provided a novel illuminator 100 having a light source (10) and optics (20). The light source (10) and optics have light emitting and light path modifying components (11, 12, 21, 22, 23), which form two different combinations. The components of the first combination cooperate so as to output a first output light pattern (A) having a width in a plane and the components of the second combination cooperate such to output a second output light pattern (B) having a width in said plane. The width of the second output light pattern (B) is narrower than that of the first output light pattern (A), whereby the total output light pattern (A+B) of the illuminator (100) is a sum of the output light patterns (A, B) produced by the combinations of components (11, 12, 21, 22). The illuminator may be a flight obstacle illuminator or a navigational aid.
