The Grover Stuttertone®: Setting the Standard for Emergency Vehicle Signaling

For almost a century, the Grover Stuttertone® line of air horns has defined what it means to be heard in an emergency. Built with unmatched precision and reliability in the United States, the Stuttertone® didn't just enter the market—it revolutionized it. Before our horns hit the market, emergency vehicle signaling was inconsistent and often ineffective. We changed that forever.

The Stuttertone® quickly became the gold standard across the globe, trusted by fire departments, rescue fleets, and law enforcement agencies who needed a signal that could cut through traffic and command attention. Its unmistakable Stuttertone® and powerful cadence is not only iconic but lifesaving.


Over the years, many have tried to imitate our work with cheaper materials and shortcuts. They have failed. Why? Because the Stuttertone® is more than just a horn.


It is a commitment to quality, a legacy of innovation, and a symbol of trust built over generations. No shortcut can replicate that.
