Abstract
A hand-held wafer-like signal which is essentially flat octagonally shaped with a handle at the lower end. It has a front side and a back side. The front side is a unitary construction made by plastic injection molding and has a reflector surface, one-half of a handle and a one-half of a cylindrical light housing which is essentially perpendicular to the reflective surface. There is a back side which is also made by injection molding and also has a reflective surface inside an octagonal frame, one-half of a battery container and one-half a cylindrical light housing. The one-half front and back sides are secured together as by screwing and when assembled it becomes a lightweight weatherproof hand-held signal.
