Tractor Trailer Air Horn

Feature-Forward Power and Control

BossHorn’s tractor trailer air horn pairs a high-output air compressor with genuine metal train trumpets and our custom control PCB. You get three selectable volume levels, motor overheat protection, and battery deep-discharge protection — all hand-assembled in the U.S. The wireless remote reaches up to 2,000 feet, and the unit accepts batteries from 15+ major tool brands for true cordless, no-install operation.

Purpose-Built Portability

The tractor trailer air horn is ready out of the box and requires no mounting or hardwiring. It feels solid in use — the trumpet tone carries clear and deep, not tinny — and it’s simple to swap batteries between jobs. Ideal for truckers who need a reliable alert on long hauls and farmers who want a quick portable signal around fields.
