Train Horns for Vans

Engineered Loudness & Control

BossHorn’s van horn train pairs industrial air compressors, real metal train trumpets, and a custom control PCB for precise performance. The PCB enables three selectable volume levels, motor overheat protection, and battery deep-discharge protection. Trigger the horn with a wireless remote from up to 2,000 feet, or swap in a compatible tool battery from brands like DeWalt, Milwaukee, or Ryobi. Each unit ships ready to use and is hand-assembled in the USA for field service reliability.

Portable Convenience & Real-World Use

Van horn train units attach to a same-brand cordless battery, so there’s no wiring or permanent mounting. Expect instant, blunt sound that cuts through traffic noise and weather — useful for convoy signaling, roadside assistance, or clearing a campsite. The feel is solid and throttle-like: a punchy blast with metal resonance from the trumpets. Buy a kit with a battery for true plug-and-play convenience on work vans or weekend rigs.

Built for Durability and Ease

Need a loud, cordless horn for your van that works across long distances and rough conditions?

We use genuine cordless tool components so parts feel familiar and last. Every BossHorn is hand-assembled in the U.S. by technicians who care about fit and finish. Our custom PCB limits motor heat and protects batteries from deep discharge. We tested remotes for range and reliability before shipping. Warranty coverage lasts one year, because we stand behind what we build.

The van horn train is compact, weather-resistant, and designed for quick battery swaps. It’s meant to be carried, used, and trusted whether you’re on a jobsite or a backroad drive.
