ABSTRACT:
A rotary reflective marker (10) is provided which may be mounted on either a stationary or a mobile object. The marker has a rotatable member (12) and includes a light reflective portion (13) arranged in a generally spiral or intermittant pattern so that as the member (12) revolves the spiral pattern of the light reflective portion (13) appears to move causing the marker to be more visually perceptible to an observer at a distance. A weight braking system is also provided to control the rotational speeds of the member (12). The marker may be powered by ambient wind forces or by conventional mechanical mechnisms.
