Tuned Performance & Rugged Components
BossHorn car air horn systems pair a high-output air compressor with genuine metal train horn trumpets and a custom control PCB. You get three selectable volume levels, motor overheat protection, and battery deep-discharge safeguards. The kits run on tool-brand batteries (DeWalt, Milwaukee, Ryobi, etc.), include a wireless remote with up to 2,000-foot range, and are hand-assembled in the U.S. — all engineered so the car air horn sounds like a real train blast while staying safe for repeated use.
Ready Out of the Box
The car air horn arrives complete or battery-ready so you can pull it out and use it immediately. It’s cordless, portable, and simple to operate—clip in a compatible battery or buy a kit with one included. Great for driveway safety signaling, convoy alerts on backroads, or clearing a crowded trailhead; the horn’s metal trumpets give a clear, attention-grabbing tone that cuts through wind and traffic noise.
Practical Considerations Before You Buy
Looking for a loud car air horn that won’t need hardwiring? Consider range, battery compatibility, and thermal protection when choosing a kit. BossHorn is the first to invent drill-powered train horns with wireless remote control. We build with real metal trumpets salvaged from industry components. Every unit is hand-assembled in the U.S. Our custom PCB gives selectable volume so you’re not stuck at full blast. We protect batteries from deep discharge and motors from overheating. You don’t need tools or mounting—just a compatible battery and a place to safely sound it.
