ABSTRACT:
This invention is a combination of known elements for a new use. This is an adaptation of the old shadow light principle coupled with time to cause three different light apertures to be aligned in a lighted window effect, thereby indicating a previously programmed marking to remind the owner of hourly, daily or weekly radio, television programs, appointments or meetings.
