Abstract
Provided herein is a retroreflective article comprising a retroreflective film and a plurality of isosceles triangular pyramid prisms embossed on the back surface of the retroreflective film. The prisms are configured such that the article reflects an incident light beam into two reflected light beams that are offset from and on opposite sides of the incident light beam. The two reflected light beams can provide two viewing zones located at different positions relative to the incident light beam source.
