So, RHW don't have lights at night... except for the bridges.
Poor drivers :(
I found only a really old light mod that I am not sure it even work with NAM anymore, specially considering how much RHW changed.
So, anyone know how I put lights in my daytime gorgeous RHW-10s network?
I recommend one of Mandelsoft's Light Replacement Mods (LRM). Included in each set is a number of ploppable lights for the RHW network.
Try using these?:

Even the great Haljackey uses 'em :)
