Truck Air Horn

Pro-Level Performance Built for Real Use

BossHorn truck air horn systems pair a high-output air compressor with genuine metal train trumpet trumpets and our custom control PCB. Expect three selectable volume levels, motor overheat protection, and battery deep-discharge safeguards. The unit runs on standard cordless tool batteries from brands like DeWalt or Milwaukee, works up to 2,000 feet with the wireless remote, and needs no vehicle installation—hand-assembled in the USA for reliable, loud performance when it matters.

Everyday Use, Clear Outcomes

The truck air horn is ideal for roadside safety, farm work, and off-road signaling—loud, immediate, and portable. You’ll notice the metallic, focused blast cuts through wind and traffic noise; crews appreciate the instant attention it gets, and weekend riders love the easy swap of a compatible battery. No drilling into a vehicle, just clip in power and go—great for quick alerts on construction sites or for trail escorts.
