We present a class of pairs of non-trivially conformally related solutions of Einstein-Maxwell equations that are not pp-waves. To our knowledge, this is the first such case and thus an extension of theorems by Brinkmann, Daftardar-Gejji and Van den Bergh concerning conformal transformations of solutions with null electromagnetic fields.
