If you work in a state or region that restricts POV siren use, then courtesy is really all you can rely on when responding to emergency calls. The
HA-150 Under Hood Stutter Horn Amp gives courtesy a boost by providing a loud and legal*, all weather, audible warning component to your POV light package.

This professional grade, 100 watt amplifier incorporates the power of a simulated “stutter” air horn with the reliable quality not found in
other aftermarket horn products. Its compact, waterproof design offers flexible, easy installation options for any vehicle. And at roughly the
size of a bar of soap, the HA-150 is perfect for volunteer POV’s, as well as, motorcycles, ATV’s, and marine craft.
