That critical moment when your truck needs to be heard - choosing the right horn can prevent accidents and save lives.
Heavy duty truck horns come in three main types: air horns (loudest at 120-150dB), electric horns (110-130dB), and dual-tone systems - selection depends on vehicle size, usage, and local noise regulations.
Types of Heavy Duty Truck Horns
Different horn types serve specific purposes in commercial vehicle safety.
Main categories:
- Air horns (pneumatic systems)
- Electric horns (electromagnetic)
- Dual-tone electric horns
- Train-style multi-trumpet horns
- Compact heavy-duty models
