Backup the \sound directory of the bus you’ll apply the mod.

To use it as first / main horn:

  • Extract the content of “\LjNad_PostBus_3TonesHorn_v1.0\OMSI 2\Vehicles\BusYouWantToMod\Sound\ToUseAs1stHorn” directory on the \sound directory of the bus you’d like to add the horn to.

To use it as secondary horn:

  • Make sure the bus supports the second horn (check that the files "SD_hupe_an2.wav", "SD_hupe_aus2.wav" and "SD_hupe_lang2.wav" are present in the \sound directory of the bus). Not every bus supports it.
  • Extract the content of “\LjNad_PostBus_3TonesHorn_v1.0\OMSI 2\Vehicles\BusYouWantToMod\Sound\ToUseAs2ndHorn” directory on the \sound directory of the bus you’d like to add the horn to.

    Corrected the directory hierarchy

  • How can i use it as secondary horn? Thanks in advance

    • Hello,

      Check in the \sounds directory of the bus you want to upgrade that the files "SD_hupe_an2.wav", "SD_hupe_aus2.wav" and "SD_hupe_lang2.wav" are present and copy it elsewhere as backup before extracting the one of the mod.

      The bus must support this function. Not all busses supports it. In case are not present, the chance is high that the bus doesn't support the second horn.

      Once verified that the bus supports the 2nd horn, that you have made a copy of the files mentioned above, extract the content of “\LjNad_PostBus_3TonesHorn_v1.0\OMSI 2\Vehicles\BusYouWantToMod\Sound\ToUseAs2ndHorn\” directory on the \sound directory of the bus you’d like to add the horn to, as also explained inside the readme.

      enjoy it!
