hmm...
in parts catalogue it says that one horn is for high pitch and the other one is for low pitch...
They should be working together as a dual-tone horn for the best effect...

A high-pitched sound tends to disperse more readily, while a low-pitched sound can travel further and penetrate obstacles better. Having both high and low-pitched horns ensures that the car's warning signal can be heard effectively in various environments and conditions.
