Genuine GM Part
Upgrade your GMC Sierra HD with this 4-piece Blackout Side Marker Lamp Set, designed specifically for trucks equipped with factory fender-mounted side markers above all four wheels. This premium upgrade delivers a clean blackout appearance while maintaining full OEM functionality and fitment.
Each lamp starts as a brand-new Genuine GM part, then is carefully modified and refinished in the U.S.A. by our small business. All factory lettering and stamping are shaved by hand, the surface is meticulously prepped, and a specialized paint blend is applied to create a deep gloss black light-through finish that maintains proper illumination.
Finished with an OEM-grade clear coat and polished to a clean, refined gloss, this is the factory-quality blackout upgrade your Sierra HD should have come with.
