About This File
GTA 4 (not tested in GTA 5) - This is the Federal Signal Smart Siren 2000SM (No Rumbler) siren modification for GTA 4. This siren is very commonly heard on many New York Police Department (NYPD) vehicles. This siren sounds very similar to what it's like in real life! ;) A great quality siren - great thanks to FlipSwitch Games.
Many thanks to - FlipSwitch Games
