ABSTRACT:
A retroreflective assembly includes a transparent polycarbonate housing of generally trapezoidal cross section. A channel extends upwardly from the base of the trapezoid, and the channel receives a vertically oriented strip of retroreflective sheet material. Planar side surfaces are provided at an angle with the vertical so that light from oncoming cars impinging on it will be directed downward to the retroreflective strip, whose top is spaced downward from the top of the housing to permit a thickness of material between the top of the channel on the top of the housing that is sufficient to afford structural strength to the housing. As a result, the image of the retroreflective strip is higher than its actual position, permitting relatively high visibility in a small structure of rugged construction.
