Truck Train Horn

Rugged Engineering & Real Components

BossHorn’s truck train horn pairs a high-output air compressor with real metal train horn trumpets and a custom control PCB, so you get three selectable volume levels, motor overheat protection, and battery deep-discharge protection. The unit accepts batteries from 15+ major tool brands, offers wireless remote triggering up to 2,000 feet, and needs no vehicle installation. Each horn is hand-assembled in the U.S., uses industrial-grade fittings, and is built to be ready right out of the box.

Portable Power for Everyday Use

A truck train horn is perfect when you need instant attention on the road or at a jobsite. The cordless setup means quick swap-and-go power with compatible drill batteries; no wiring, no drilling. Expect immediate, chest-level bass from metal trumpets and consistent blasts that cut through wind and traffic noise—useful for roadside alerts, farm equipment signaling, or safe convoy starts.
