Abstract
Abstract A highly visible display device has a base, a staff supported by the base, and a battery-operated signal device located at the top of the staff. A plurality of support poles are interconnected to form the staff, thereby enabling the display device to be erected and subsequently disassembled quickly and easily. A ballast bag is adapted to fit over the base in order to maintain the display device in place, for example against the action of high-speed vehicular traffic passing by the device. A flag may be secured to the staff to further enhance the visibility of the display device.
