Abstract
A luminous decorative vehicle trim insert having an opaque carrier structure. A reflective layer is disposed over the opaque carrier structure. A light pipe is adjacent the reflective layer and operably connected to a light source. An optic layer is disposed in the light pipe. A total internal reflection (TIR) protective layer is disposed over the light pipe. A diffusing layer is disposed over the TIR protective layer.
