Abstract
An electrically synchronized rotating light system comprising two or more rotating light assemblies each having an associated drive motor, there being in one embodiment a master light unit including a rotating light and drive motor which rotates the light at a predetermined rate, and one or more slave light units each including a rotating light and a slave drive motor, the master and slave units being electrically wired so the speed of rotation and phase of each slave unit is synchronized with the master unit without need for mechanical connections between the units. In another embodiment, two or more slave lights are provided, each having an associated slave drive motor, in combination with a master drive motor not associated with a corresponding light. In a further embodiment, each rotatable light has an associated motor mounted directly on the lampholder for conjoint rotation with the lampholder.
