These are OEM Quality and complete replacement units. GS took the time and detail to make sure these reflect just like OEM. To do this they had to replicate the complex diffuser which is molded into the backside of the font lens. NOT a flat acrylic cover that will stick out when installed. NOT a film that will leave you with bubbles and shrink over time exposing the factory light edges. Clean and updated look that retains the OEM feel but with a sleek twist. Fitting all 2014-2019 C7 models, they make for a quick and easy install that is sure to clean up the backend of your C7!
