FSX/P3D. Night Environment is a series of add-ons for FSX and P3D that revolutionizes the way the world looks at night. Using a series of databases it will add lights to roads and other areas. Hundreds of thousands of lights (in some Night Environment editions millions) clearly show how highways connect cities and how smaller roads meander into neighborhoods. Visual navigation at night becomes a real option and even easier than during daytime just as it often is in real aviation. Night Environment database contains many times more roads then FSX or P3D, so you will see roads at night where you will see none during daytime. All lights are potentially visible for 60 miles so large areas will light up around you. As the highway lights are raised above the surface and have a lit bitmap below them, a correct 3d effect is created.
