I often thought it would add to twilight and night rides if we had lights on the coasters as most do in the real world. Must be someway to do it in NL as they have is flight simulator and the train simulator.
The thing about doing lights though is that with the simulator right now, you can never actually have lights. All you can do is make a 3ds with a transparent beam that simulates light and then make an environment that makes everything look like it's lit up. A better example would be Buster's Megablast
