Thanks for your link!
I am interesting about it.
It is useful!

Oh, May be you can change another wheel!

Quote from danthebangerboy :

there is no 'ON' position for any of the cars, you can only flash the lights as LFS doesnt have night mode, always on lights are not needed.

There is an insim app, i thing it was called strobe or something, to make them stay on, or you may be able to set something in a profiler in some way to make them stay on.

Someone will know better than me.

Yes , you are right! Nice post
