ABSTRACT:
Triangular reflecting plastic warning devices having a hole at the top for hanging from a post or the rear of a slow-moving vehicle, a hole in each of the side legs for receiving the stub connectors of a removable sign with words such as HELP, S.O.S., STOP, SLOW, DANGER, KEEP OUT, a pair of holes on the lower rim of the bottom leg to permit insertion of legs with pins whereby the legs may be horizontal with a land surface or vertical to be pushed into the ground, and having a projecting arm with a hook for use with an automobile window. On the reverse side on the triangular border and on the letters on the reverse side of the removable sign are provided a plurality of 90.degree. apex angle cones for wide angle parallel ray reflection effective during daylight hours as well as at night. The letters are sunken with respect to the front surface of the sign to permit painting or silk screening with a different color to make the letters stand out without covering the reflecting letters.
