Abstract
Abstract A reflex reflector which when vertically oriented spatially is adapted to continuously retro-reflect incident light rays horizontally striking such anywhere within an included angle of about 180*. Units of such reflectors arranged together provides continuous reflex reflectivity over 270* or 360*. Each such reflector uses four reflective surfaces, two being adjacent one another, and two being opposed to each other and perpendicular to such adjacent two members. Each surface has reflex reflector facets adapted to retro-reflect over an angle of + OR - 45*.
