How does car horn work?
Car horn: “A horn is a sound-making device that can be equipped to motor vehicles, buses, bicycles, trains, trams (a.k.a. ... The sound made usually resembles a "honk"). The vehicle operator uses the horn to warn others of the vehicle's approach or presence, or to call attention to some hazard.”
With hundreds of vehicles on the roads today there is one feature that can piss someone off or actually warn them and possibly stop them from ending up in an accident it's called a horn. Car horns are built like a buzzer by having the steel diaphragm acting in one direction while a spring pulls in the opposite direction. This is caused by a current constantly hitting the spring back the other way causing it to vibrate. In other words a horn works by having positive and negative electrogments crash into each other. Here at Bcr Automotive most vehicles come with horns but most importantly they come with everything you need to fit your lifestyle.
