Unrestricted Air Horns + Extra Horns

This mod allows you to place the air horns in the Cabin Light, Roof Light, and Lightbar accessory slots on certain truck cabins, opening up more options for air horn placement, and air horn combos. Especially on trucks that do not have the ability to even place air horns to begin with.

This mod was designed specifically with TMP in mind, so this mod is compatible with TMP. To use the mod, load the game in singleplayer, add the horns to your desired truck after checking the list below for what trucks, cabins, and slots the horns can now be placed in. Save and close the game, launch TruckersMP, and enjoy.

Note: The Train, Mack, and Freightliner '24 horns added by this mod DO NOT work in TruckersMP. Adding them will result in the horns being removed when you enter TMP. Only the vanilla horns work with TMP. The Black counterparts to the vanilla horns are untested with TMP. Please let me know if they work.

I am NOT responsible if you abuse this mod on TruckersMP and are banned.

This mod is compatible with Convoy mode. Simply enable the mod like any other and enjoy!

The mod does the following:
* Adds new horns:
~ Train Horn with Black counterpart. Utilizes the 2019 Freightliner Cascadia default air horn.
~ Mack Horn with Black counterpart. Utilizes the Mack Anthem/Pinnacle default air horn.
~ Freightliner '24 Horn with Black counterpart. Utilizes the 2024 Freightliner Cascadia default air horn.

* Unrestricts horn placement on various trucks where applicable/possible.

Here's a complete list of the trucks, their cabin types, and in what slots air horns can now be placed:

IF you have the Western Star 57X 48 Inch XT Sleeper mod installed, there is also a Horn Adapter slot for the 48" Sleeper, but ONLY with the linked mod installed. SCS cut the 48" sleeper for the 57X before release, the linked mod restores it.

NOTE: The Horn Adapter slot for the 72" Sleeper XT cabin is currently broken and does not actually add slots. This is a vanilla bug that SCS has to fix.

Truck Mod Compatibility
I do not know what truck mods this is compatible with. All I can say for certain is that it will be compatible with truck mods that utilize SCS's accessory slot names for Cabin Lights, Rooflights, and Lightbars. I have no plans to directly support truck mods.

Once SCS Software updates and adds more trucks, depending on if whether or not those trucks have the appropriate accessory slot options, I'll update the mod to support future new truck additions.
