Drill Train Horn

Rugged Components, Smart Controls

BossHorn’s drill train horn pairs real metal trumpet trumpets with an industrial compressor and our custom control PCB. You get three selectable volume levels, motor overheat protection and battery deep-discharge protection built into the system. The remote works up to 2,000 feet, and units accept batteries from 15+ major tool brands like DeWalt and Milwaukee, so you’re using familiar power with professional-grade output.

Ready Out of the Box

The drill train horn arrives assembled and requires no vehicle mounting — just snap on a compatible battery or buy a kit with one included. It’s ideal for quick setups at tailgates, construction sites, or ranch work, delivering immediate, attention-grabbing sound without wiring or permanent installs.

The drill train horn blends portability with professional audio output, so you get the raw sound of a full-sized horn without permanent installation. That means faster setups for events, clearer signals on farms and job sites, and a tough, serviceable system when you need it most.
