Vehicle Air Horn

Performance-Driven Features & Real Benefits

BossHorn vehicle air horn systems pair a high-output air compressor with real metal train trumpets and a custom control PCB. You get three selectable volume levels, motor overheat protection, and battery deep-discharge protection — all controlled via wireless remote out to 2,000 feet. The units accept genuine cordless tool batteries from DeWalt, Milwaukee, Ryobi, and others, so you can swap power packs fast and avoid wiring or mounting hassles.

Everyday Use: Built for No-Install Convenience

The vehicle air horn arrives ready to blast — no drilling, no permanent mount, no garage time. Clip in a compatible tool battery or buy a kit with battery included and you’re set for tailgates, road emergencies, farm work, or boat use. Expect instant, directional sound that grabs attention; useful for stalled cars, convoy signaling, and clearing a path on rural roads.
