Components are corrosion-resistant and the compressor features automatic pressure control and overload protection. The package supplies the core hardware required for installation so you can upgrade virtually any 12V vehicle with a train-style horn voice.\u003c\/p\u003e\n\n\u003ch3\u003eHow loud is the horn and what environments is it best for?\u003c\/h3\u003e\n\u003cp\u003eThe horn reaches approximately 150 decibels, engineered to cut through highway noise, heavy traffic, and harsh weather conditions where standard car horns might go unheard. Because of its volume and directional projection, it’s particularly suited for long-range warnings, ranches, industrial sites, and marine settings where clear signaling matters.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRated output: ~150 dB for strong penetration over distance\u003c\/li\u003e\n  \u003cli\u003eFour tuned trumpets for blended, train-like tone\u003c\/li\u003e\n  \u003cli\u003eEffective in rain, wind, and high ambient noise\u003c\/li\u003e\n  \u003cli\u003eNot intended for prolonged indoor use or close-range exposure\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat does the air system include and how does pressure control work?\u003c\/h3\u003e\n\u003cp\u003eThe kit contains a 12V air compressor, a 0.8-gallon (≈3 L) welded tank, solenoid valve, tubing, gauge, and four trumpet horns.
