Air Train Horns

Power, Control, and Real-World Components

BossHorn systems pair industrial-grade metal trumpets with a high-output compressor and a custom control PCB for three selectable volume levels, motor overheat protection, and battery deep-discharge safety. These air train horns run on real cordless tool batteries from brands like DeWalt and Milwaukee, give instant wireless activation up to 2,000 feet, and are hand-assembled in the U.S. That means reliable, repeatable blasts without permanent vehicle installs—take them to the job site, the trail, or the yard.

Built for Use — No Installation Required

Air train horns connect to compatible tool batteries or come as a full kit, so you’re not splicing into wiring or drilling mounts. Expect loud, attention-grabbing output that carries across fields and campsites, a compact compressor that fits in a trunk, and simple one-handed operation. Ideal for off-roaders warning trail traffic or ranchers signaling across property lines.
