This is wrong, the trailer was never updated to the new system. You can't connect it to the trucks currently in game or the Segra.
Nah this was an easy fix, I tried to do the hitch implementation some time before though and couldn't figure it out
(sorry for bumping) hi so i added kinda bloomy lights to this to make it look better only problem is that reverse light is kinda yellowish and its almost the same colour as turn signals, but its still a noticeable difference, idk how to fix this as i just used material editor to make the lights bloomier not a big deal in the file, u need to place a dot in between the "main" and "materials" file for it to work properly, like this: "main.materials.json" then place it in "youruser > appdata > local > beamng.drive > 0.32 > vehicles > eu_trailer" if theres no "vehicles" folder inside 0.32, create a folder with the same name if theres no "eu_trailer" folder inside vehicles, create a folder with the same name once again, srry for bumping also plz use ch4rl3s's fixed version on this exact same page for turn signals to work properly
Oh then the Fictional Trucking & Service mod's author should take care of that problem, the author of this HSP mod has been gone for over almost 2 years
