Abstract: A changeable sign comprises an enclosed outer housing and inner changeable number display areas. The number display areas are comprised of vertically spaced sections, each including a plurality of rotatable horizontal flaps. The flaps are rotated by motors which may be controlled on-site or remotely using telephone, pager or radio remote controllers. Different arrangements of number displays may be provided to display the time, temperature, single digit numbers, multiple digit numbers and decimals as well as other characters. The sign has a compact construction and is weather resistant.
