The project was designed by the artist LeoVillareal, who named the project thebaylights, which means the lights of the bay. The entire project consists of 25,000 1-inch LED lights, which are 1.8 kilometers long and are fixed on the suspension cable of the bridge. The project cost $8 million and it took a total of two years to lay.
Each lamp is controlled by a computer program, and a variety of dynamic patterns can be combined to ensure that the images that are broadcast are absolutely not duplicated. The pattern of LED lights is based on a randomly generated image program that requires no manual intervention.
