Abstract
An automotive light guide that displays subsurface engraved indicia to create an optical branding feature or another illuminated design element. In one implementation, the light guide has a body with a primary viewing outer side and a plurality of microablation sites located within the body. From a first viewing angle with respect to the primary viewing outer side, the plurality of microablation sites are configured to appear in a first indicia pattern, and from a second viewing angle, the plurality of microablation sites are configured to appear in a second indicia pattern. In another implementation, the light guide has a body with a planar engraving outer side and a rounded primary viewing outer side. The plurality of microablation sites are etched through the planar engraving side and are viewable as an indicia pattern through the rounded primary viewing outer side.
