This update is a complete re overhaul of the skin, apart from the livery who stayed the same, the Light bar and the code that was with it was completely remade and thus require a fresh new install.
I suggest you delete the old safety car as I changed the skin name to a more obvious one.
Hello,
Quick update because I forgot to put the Preview and skin icon.
If you already have the V1.1 of the mod, you don't need to reinstall it, it doesn't change the light bar or the coding.
