300W Octagonal Thin Horn

300W Octagonal Thin Horn 300W Octagonal Thin Horn is a high-power warning sound device designed for vehicles and engineering machinery. Adopting octagonal thin shell structure, it outputs loud and clear warning sound with stable 300W power rating. The compact thin profile saves installation space and is easy to mount on limited vehicle body areas. Built with high-quality vibration diaphragm, it delivers penetrating audio to alert surrounding personnel, and reinforced shell structure protects internal components against external impact, widely used for trucks, construction machinery and special service vehicles. This 12V24V Wide-Voltage Alarm supports both 12V and 24V power supply, adapting to most gasoline and diesel vehicle electrical systems. The wide voltage design keeps stable working state under voltage fluctuation and avoids burnout caused by unstable power. Optimized internal circuit reduces energy consumption, and over-current protection extends the service life of the horn u…
