Abstract
Aspects of the present disclosure involve a transparent structure. The structure may include at least one light source, a transparent light-carrying guide layer optically coupled with the at least one light source. The structure may include refractive layers where a light absorbing feature is operably associated with the light-carrying guide layer to absorb any light not internally reflected in the light guide layer, at least adjacent the light source.
