Train Horn For Car

Handcrafted Power and Smart Controls

BossHorn’s train horn for car brings real industrial components—metal train trumpets, a high-output compressor, and our custom control PCB—into a cordless package. You get three selectable volume levels, motor overheat and battery deep-discharge protection, plus wireless triggering up to 2,000 feet. Each unit accepts industry-standard cordless batteries from top brands so there's no wiring or vehicle install required. It’s loud, engineered for repeat use, and hand-assembled in the U.S.

Ready Out of the Box for Everyday Scenarios

For a train horn for car, ease matters: snap on a compatible tool battery or buy a kit with one included and you’re done. Expect immediate, attention-grabbing sound for clearing trails, alerting at crossings, or commanding attention at events. The system feels solid in hand, fires instantly, and keeps going thanks to industrial-grade valves and metal trumpets designed for repeated use.
