Automotive Train Horn Kits

Engineered Loudness, Portable Convenience

BossHorn automotive train horn kits pair real metal trumpets and a high-output compressor with a custom control PCB so you get selectable volume levels, motor overheat protection, and battery deep-discharge safety. The system runs off common cordless tool batteries (DeWalt, Milwaukee, Ryobi and more) and includes a long-range wireless remote. No mounting or vehicle mods required — just snap on a compatible battery and you’ve got professional-grade horn output that travels with you.

Designed for Real-World Use

Automotive train horn kits give instant audible presence whether you’re on a ranch, at a rally, or pulling a trailer. You’ll notice the solid metal trumpet tone, fast compressor spool-up, and a control board that prevents motor burnout. Use cases: safety signaling on farms and off-road groups, or clearing a crowded campsite. The kit feels tactile and mechanical — a proper, audible tool rather than a buzzy novelty.
