“The V1 presshorn literally scares my passengers. It’s perfect for my HLF 20 fire truck mod.” – FeuerJohn (Emergency-Planet)

“Installation is fiddly, but once you hear the echo of Tone 2 off a highway barrier in the rain, you’ll never go back to American sirens.” – LSFD_Captain

The Hansch Typ 620 v1 is distributed as a manual install pack with an optional auto-installer for GTA V (via OpenIV).
