Train Horns for Cars

Industrial Components, Everyday Control

BossHorn’s car train horn combines real metal trumpets, a high-output air compressor, and our custom control PCB into a handheld-ready package. You get three selectable volume levels, motor overheat protection, and battery deep-discharge safeguards. The system runs on compatible cordless tool batteries and includes a wireless remote with up to 2,000 ft range — no vehicle wiring, no mounting, ready out of the box for instant, powerful sound when you need it.

Portable Power and Practical Use

The car train horn is designed for quick deployment: snap on a compatible battery and you’re set. It sounds raw and metallic — the kind of punch that cuts through road noise — and it’s ideal for campsite warnings, emergency signaling, or grabbing attention at meets. Lightweight enough to carry, rugged enough for mud and grime, and usable in short bursts without overheating thanks to built-in motor protection.

That mix of real metal hardware and electronic safeguards makes it a dependable choice when you need loud, portable signaling.
