What is Howo WG900027002 Air Horn

Air horns are essential signal components for heavy trucks.

The WG900027002 is a dual-tone model specially made for SINOTRUK Howo series trucks.

It runs on the vehicle's compressed air system, delivering loud, distinct sound to alert other road users during regular runs and emergencies.

Built tough, it fits Howo and other mainstream Chinese heavy trucks perfectly as a direct OEM replacement.

How Does the Wiper Motor Assembly Work

This dual-tone air horn features a simple, reliable structure:

Air intake: Draw compressed air from the truck's air system.
Valve action: The built-in 24V solenoid valve opens when activated, feeding air into the two horn bodies.
Sound generation: High-pressure air vibrates internal diaphragms to produce dual-tone sound that carries far.
Consistent performance: Premium internal seals keep air pressure stable, with no air leakage during use.
