Möbius strips with one, two, three, and four, half-twists are shown to be generic features of three-dimensional (nonparaxial) elliptically polarized light. The geometry and topology of these unusual singularities is described and the multitude of winding numbers that characterize their structures is enumerated; probabilities for the appearance of different configurations are presented.
