A taillight article (100) including at least two optically clear light guides (110, 130) stacked on each other to provide vehicle signal function is described. The taillight article comprises a first optically clear light guide (110) having a 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), and a plurality of light extraction features (116) on or within the first optically clear light guide (110), the light extraction features (116) configured to direct light out through the emission surface (112); a second optically clear light guide (130) having an light emission front surface (132) and an opposing rear surface (134) and a side surface (138) separating the front surface (132) and the rear surface (134) and a plurality of light extraction features (136) on or within the second optically clear light guide (130), the light extraction features (136) configured to direct light out through the emission surface (132) a first low index layer (150) separating the rear surface (114) of the first optically clear light guide (110) from the front surface (132) of the second optically clear light guide (130), the first low index layer (150) having an index of refraction being less than an index of refraction of the first optically clear light guide (110) and the second optically clear light guide (130); a first light source (120) configured to direct light into the side surface (118) of the first optically clear light guide (110), the first light source (120) indicating a first signal function; a second light source (140) configured to direct light into the side surface of the second optically clear light guide (130), the second light source (140) indicating a second signal function; and a light reflection element (160), where the second optically clear light guide (130) is disposed between the first optically clear light guide (110) and the light reflection element (160).
