Hello, I have been using your mod for a very long time and like it. But probably due to some changes by SCS, there is no sound output from the horns anymore. They are mute. Can you check where the problem is when you get a chance?
Then maybe you could update the IFTA stickers. It only goes until 2020, but it's really only a small thing.
What I think would be great is if you could install a cabin light for night-time driving. Maybe in several colours. There are different tastes. In RL, I always liked blue night lights more than red ones. It's no different in the game.
