A taillight article (100) including an optically clear light guide (110) having an light emission front surface (112) and an opposing rear surface (114) and a side surface (118) separating the front surface (112) and the rear surface (114) is described. A first light source (120) is configured to direct light into the side surface (118) and indicate a first signal-function. A plurality of light extraction features (116) are on or within the optically clear light guide (110) and are configured to direct light from the first light source (120) out through the emission surface (112). A light reflection element (130) is spaced apart from the rear surface (114) and defines a cavity (135) that is observable by a viewer.
