Special transport signs and lights mod is on the repo : https://www.beamng.com/resources/special-transport-signs-and-lights-for-the-t-series.20401/
Tonight at 6pm (French time), a premiere will take place on my channel (don't forget to activate the reminder)! There is going to be the pilot episode (test) of a new series that I will try to make last on the long term on my channel. This new series is called "Today In Beamng". Each episode of a variable length of less than 10 minutes will be about a topic related to BeamNG and will be humorous (I will try to make you laugh at least xD). Since it's a pilot episode there will be things to change so don't hesitate to tell me!
I made a similar thing (not released) a long time ago but yours is way better, this is the only picture of it I could find:
Oh well it was not perfect but it was working quite well that's the main point, GG ! --- Post updated --- ^^
