Dual Trumpet Automotive Warning System with Built-In Compressor – 150 Decibel Alert for Cars, Trucks, SUVs & RVs | Thomler
Command Attention on Every Drive
When a standard horn just won't cut it, this dual-trumpet automotive alert system delivers a thunderous 150-decibel warning signal that stops traffic in its tracks. Engineered with chrome-plated metal construction and an integrated 12-volt compressor, it mounts quickly to any vehicle and withstands rain, snow, and road debris without losing volume. Perfect for highway merging, emergency alerts, or simply making your presence known, this compact kit replaces factory horns with professional-grade sound that rivals train and semi-truck systems—yet installs in minutes with basic hand tools.

Why You Need This
- Instant Collision Avoidance: The ear-piercing dual-tone blast cuts through music, closed windows, and traffic noise to alert distracted drivers, cyclists, and pedestrians before accidents happen.
- Weatherproof Metal Build: Chrome-plated zinc trumpets and a powder-coated compressor housing resist rust, ice, and UV damage for years of reliable service in any climate.
- Universal 12V Compatibility: Works with cars, trucks, vans, SUVs, RVs, motorcycles, tractors, buses, and boats—any vehicle with a standard 12-volt electrical system.
- Drop-In Installation: Includes mounting brackets, air hose, relay, and hardware so you can wire it into your existing horn circuit and secure it to the radiator support or fender in under an hour.
- Compact Yet Commanding: Twin trumpets measure just 17.7 × 3.9 × 3.9 inches overall, fitting tight engine bays while producing sound levels that exceed most factory systems by 40+ decibels.
- Eye-Catching Finish: Polished chrome trumpets and a glossy red compressor add a custom touch under the hood, blending performance with show-quality aesthetics.
Built to Perform Mile After Mile
Mount it once and forget it—this system's all-metal construction laughs at potholes, car washes, and winter road salt. The relay-activated compressor cycles instantly when you press your steering-wheel button, so there's zero lag between activation and alert. Whether you're navigating dense city intersections, passing on two-lane highways, or clearing wildlife from rural roads, the twin-trumpet configuration ensures your warning is heard from blocks away. Installation taps your factory horn wire (no cutting or splicing), and the included mounting hardware adapts to most radiator supports, core supports, or bumper brackets. You'll enjoy free shipping across the United States and a 30-day return window if it doesn't meet your expectations—though once you hear it, you'll never go back to a stock horn.
