Not sure if aircraft other than the A320neo are affected.
Strobe lights do not create a flashing strobe effect when flying in IMC. These in combination with landing lights should potentially disorient a pilot flying in IMC.
Picture below of the strobe light on, and the wing light on. The wing light floods the air with ambient light in the cloud…while the strobe (which is far more powerful) is only a small dot in comparison.
