These are aftermarket smoked headlamp covers designed to fit 1973-1980 C-series Chevrolet and GMC trucks (C1500, C2500, C3500). They’re made from durable acrylic/composilite material and are custom-molded to slip over the stock headlight assemblies, giving your truck a sleek, darker aesthetic while helping protect the lenses from rocks and debris. Installation is straightforward with included hardware and instructions, and no drilling or permanent modifications to your vehicle are required.
