ABSTRACT:
A message display sign apparatus includes a display panel having front and rear faces, a multiplicity of light emitting elements disposed on the front face of the display panel for displaying a built-in message on the display panel being defined by groups thereof being arranged to form the letters of the two words, a mounting panel having upper and lower faces, and a hinge pivotally interconnecting an edge of the display panel to an edge of the mounting panel such that the display panel and mounting panel can undergo pivotal movement relative to one another between a message display position in which the rear face of the display panel is angularly displaced away from the upper face of the mounting panel and a storage position in which the rear face of the display panel is disposed adjacent to the upper face of the mounting panel. The sign apparatus also includes an electrical control circuit connected to the light emitting elements and operable to cause alternating illumination of selected ones of the groups of light emitting elements and thereby of the letters of the two words defined by the groups of light emitting elements so as to flash the built-in message formed on the front face of the display panel.
