This should be in Misc, not "vehicles". And the siren sounds like "Smile, Haggard!"

@krashadam No this is good. :)

how do i add this to the ecto 1 mod i'm using and the instructions need to be clearer as the modder says what to do with the vehicles folder and the vehicles.oac file but not what to do with the sirens files folder or am i looking at it wrong

how can i use the siren on the Ecto ? plz help
