Really nice 3D model. You can use it even without smooth. But in case you wanna do a close up, you can add smooth because the topology is ready. Do not apply smooth in the text! Also the text is collapsed, you don't need the font. About materials, I did it in c4d with redshift, but I didn't export them, because they are simples, just color and roughness.

There is UV maps for almost all of the objects! For the green lights, you can create a photoshop file and map it using a plane in front view.
