ABSTRACT:
The invention comprises a vehicular wide turn warning device having a placard with a warning printed thereon. The placard also has mounted thereon a strobe lamp and a plurality of light-emitting mechanisms, the light-emitting mechanisms being arranged to form an arrow having a point and a tail. The invention also comprises a control circuit for operating the light-emitting mechanisms and strobe lamp mounted upon the placard. The control circuit is arranged such that the light-emitting mechanisms forming the arrow are sequentially and cyclically illuminated beginning with the light-emitting mechanisms forming the tail of the arrow and preceding to the light-emitting mechanisms forming the head of the arrow. The strobe lamp is cyclically illuminated in conjunction with the light-emitting mechanisms forming the arrow. A manually operable switching means located adjacent a driver of a vehicle activates a control circuit for the vehicular wide turn warning device. The vehicular wide turn warning device is utilized by mounting at least two of the vehicular wide turn warning devices upon a vehicle, at least one of the devices being placed upon the rear of the vehicle and at least one more of the devices being placed upon one of the sides of the vehicle. By operating the manually operable switching means the control circuit is activated and the vehicular wide turn warning device operates so as to inform motorists of an imminent wide turn to be performed by the vehicle upon which the vehicular wide turn warning devices are mounted.
