We need this siren for gta 5. Many fire departments still use it. I think the alternate(when you hit the horn botton while siren is on) should just be an airhorn sound with the siren still in the backround. Classic America right there. The federal g is still in service and has been since around the 60's, so yeah it needs to be in gta.
IF this is in the wrong section, please help me put it in the right one. Posting a topic was confusing to me.
