The present embodiments relate to an aircraft 100, and, more particularly, to an aircraft 100 with an illumination system that pulses light 130 at rotating blades 108. The aircraft 100 may include a thrust producing unit 103 with a plurality of rotating blades 108 that rotate at a first frequency. First and second rotating blades 108a, 108b of the plurality of rotating blades 108 may be indistinguishable from each other by the human eye when rotating at the first frequency. A light source 120 may be installed on a fixed surface 125 of the aircraft 100 and may pulse light 130 towards the plurality of rotating blades 108 at a second frequency. The second frequency may be selected dependent on the first frequency such that first reflections 140 off the first rotating blade 108a are distinguishable by the human eye from second reflections 140 off the second rotating blade 108b.
