Illuminated traffic control paddle
Abstract:
A traffic control paddle includes a frame with a handle and a head having two sides. The head has a perimeter, a face inset within the perimeter, a surface on the face carrying literal indicia, and an upstanding lip extending around the perimeter and projecting above the face by a first distance. Two spaced-apart light-emitting diodes in the face are seated in annular projections, each of which projects above the face by a second distance. The handle carries batteries and a switch to provide power to the light-emitting diodes. The light-emitting diodes are spaced above and below the literal indicia on the face and are programmed to blink.
