So recently we have gotten some new fire and ems vehicles. New of course we have the ladder truck, engine, ambulance as addons and our brush truck to replace the in game firetruk. Now thats the only vehicle that has the correct fire siren. The others have just the regular police siren. How would i go about changing the siren on the other trucks to be the correct one.

at a guess maybe
change the siren settings in carvariations to fire engine

  </plateProbabilities>
  <lightSettings value="1" />
  <sirenSettings value="1" />
</Item>

Ill try that but im pretty sure the siren settings changes up the actual lights.

Did this work?

No it didnt those settings are for the actual lights i know it possible to do this but im just like stuck on where and what it is.

Was this issue ever solved? (And if so, How?)
