EAFC 12V Air Horn Snail Electric Dual-Tone Loud Alarm Car Boat Kit 2pcs

EAFC 12V Air Horn Dual-Tone Loud Signal Features and Installation

Your EAFC 12V Air Horn operates at nominal voltage across standard automotive electrical systems, with dual solenoid coils producing high and low frequency tones that cut through highway noise and marine environments. The snail horn design uses precision-cast zinc alloy chambers that resist corrosion and maintain acoustic tuning across temperature fluctuations from minus-10 to plus-60 degrees Celsius. Each horn pair includes protective diaphragm assemblies rated for continuous operation, so you can activate the loud alarm repeatedly without thermal damage or voice degradation. The complete boat and motorcycle kit supplies both horns, a relay module with weatherproof connector, and stainless steel mounting brackets that fit standard bulkhead and frame attachment points. Installation takes approximately 30 minutes using basic hand tools, and the included wiring diagram guides you through positive battery feed, ground return, and switch circuit integration.
