Abstract
Reflex pins for use in the manufacture of reflector assemblies or surfaces have three faces, the relative position of each face with respect to adjacent faces is 120 .degree.. According to the disclosure, selected cube faces of pins are cut to an angle that is adjusted from the convention angle of 120.degree. whereby light reflected from a product of such reflex pins is redirected or redistributed from one area of the zone of reflectivity to substantially increase the intensity of light to the location of a viewer or a recording device's light sensitive element at another area of the zone of reflectivity. A method of making such pins is also disclosed.
