Lorry Air Horn

Engineered Performance You Can Hear

BossHorn lorry air horn systems pair a high-output air compressor with real metal train trumpets and a custom control PCB for reliable output. You get three selectable volume levels, motor overheat protection, and battery deep-discharge safeguards. The unit runs off common cordless tool batteries from brands like DeWalt and Milwaukee, and the wireless remote reaches up to 2,000 feet. No wiring, no permanent mounting — just clip in a battery, press the remote, and the lorry air horn delivers professional-grade volume on demand.

Built for Real-World Use

The lorry air horn sits ready in the cab, perfect for rural deliveries, roadside safety, or clearing a busy loading dock. It feels solid—metal trumpets ring sharp and the compressor cycles with a confident, mechanical pulse. Benefit: instant, attention-grabbing sound without vehicle mods. Use case: drivers who move between jobs and need a portable alert, or fleet managers who want the same kit across multiple trucks.
