Train Horns For Semi Trucks

Power, Control, and Real Metal Sound

BossHorn train horns for semi trucks pair a high-output air compressor with genuine metal train horn trumpets for an unmistakable tone. The custom control PCB gives three selectable volume levels, motor overheat protection, and battery deep-discharge safeguards. Use compatible tool batteries from DeWalt, Milwaukee, Ryobi and others, trigger the horn with a wireless remote up to 2,000 feet, and enjoy a fully portable setup that needs no vehicle installation—hand-assembled in the U.S. for practical, loud performance.

Ready-to-Use Compatibility and Everyday Utility

BossHorn systems plug right into the batteries you already own, so setup is literally a snap; this makes train horns for semi trucks ideal for truckers who switch locations or contractors who need a quick signal on a site. Expect a raw, metal-backed blast you can hear over diesel engines and wind. Use cases: highway warning, yard clearing before backing, or signaling a convoy on remote roads.
