ABSTRACT:
A plurality of open-ended tubular members are movably mounted on a tripod-type base. Each member has a lens mounted to the front end thereof. A plurality of control rods, each independently supporting a different one of a plurality of colored or clear light sources, are located behind the lens. To permit variations in the projected image, each of the rods is individually movably mounted on a disc which is, itself, adjustably positionable within the member. The color coded rear ends of the rods and the disc position adjuster are externally accessible to permit manual positioning thereof. A flasher circuit is provided for intermittently energizing the light sources. A dimmer may also be provided to control the frequency of the light source energizations. Lights of a non-blinking variety can also be used to create stationary light patterns.
