What's the blue light for?

@EoF
I looked into the con file of the mod that allows offset placement, but it uses code that is not in the official wiki (the official wiki doesn't introduce the code that allows offset), and I can't write code, so I can't do it.
I don't feel comfortable copying and pasting the entire code written by others.
Or will you offer to code it for me?

Ok I get that. But this mod was able to do that and maybe it can be helpful: https://steamcommunity.com/sharedfiles/filedetails/?id=2128789147

@EoF
It was technically impossible.
Draw a new track on the right side and install it.

Hi, can you please add an option to put the sign on the right side? Thank you!
