I did create a mod for changing the light scene.
Now all vehicles with correctly defined lights are not changing the lightness of buildings around including rails, transports and tiles.
Problem is based in instanced renderer. The mod works very efficiently considering that creates many new shadows from close distance.

I'm still searching how to hook to the render pipeline without Harmony, for most of the stuff is the reflection enough including weather color changes.
Much better will be if the Day-Night cycle will be implemented directly in game, but this is at least, what I can do now.
