Semi Truck Air Horn

Performance Features & Real-World Benefits

BossHorn semi truck air horn uses a high-output air compressor driven by real cordless drill batteries and genuine metal trumpet assemblies to deliver clear, powerful blasts. The custom control PCB gives three selectable volume levels, motor overheat protection, and battery deep-discharge protection. Wireless remote range reaches up to 2,000 feet for safe, hands-free operation. Everything is hand-assembled in the U.S., so you get industrial-grade components and straightforward, no-install use out of the box.

Portable Power & Everyday Use

Semi truck air horn delivers an attention-grabbing, low-end blast—ideal for lane-change warnings on busy highways or alerting other drivers when a stalled rig needs space. Attach a compatible brand battery, or buy a complete kit; no drilling or mounting required. The metal trumpets produce a crisp, resonant tone you can feel, while the lightweight compressor and cordless setup keep the unit easy to carry between trucks or around the yard.
