Commercial vehicles operate in challenging environments where standard car horns simply aren't effective. At FHL GBSY JS-TECH, we engineer specialized horn solutions that meet the unique demands of heavy-duty transportation.
Truck horns require 115-150dB output to overcome ambient noise at highway speeds while maintaining strict frequency control - our advanced electromagnetic and air horn systems deliver this critical safety margin without excessive noise pollution.
Meeting the Demands of Heavy-Duty Vehicle Horn Regulations
Commercial vehicle horns must satisfy more stringent requirements than passenger cars, with specific standards for different vehicle classes and operating conditions.
Key regulatory benchmarks we meet:
- EU Regulation No. 28 (120dB minimum for trucks)
- FMVSS Standard No. 121 (130-150dB for Class 8)
- China GB 15742 (125dB for commercial vehicles)
- ECE R118 (waterproof performance)
- ISO 5122 (frequency control)
