The present disclosure relates to a vehicle indicator lighting assembly or other lighting device for providing dual-color outputs in a lit state and an unlit state, respectively. Specifically, a color of a lighting device may be controlled such that an unlit state may communicate a desired color corresponding to a surface of a component of the lighting device. For instance, the lighting device can include a light guide having one or more decoupling regions and a bezel having one or more effecting facets arranged relative to the light guide. The light guide may be optically-coupled to a light source. The one or more effecting facets may be designed such that, when the lighting device is not illuminated by the light source, a color of a surface of the one or more effecting facets is displayed to an observer in a trailing vehicle by reflection of ambient light from an environment external to the vehicle.
