Do Car Horns H and L Indicate Left and Right?

[McAutumn]

Car horns H and L do not indicate left and right. Concept: The horn is the acoustic signaling device of a car. During vehicle operation, the driver emits necessary sound signals as required by regulations to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used for urging movement and conveying signals. Principle: An automotive electric horn produces sound through the vibration of a metal diaphragm. It consists of an iron core, magnetic coil, contacts, armature, diaphragm, etc. When the driver presses the horn switch, current flows through the contacts to the coil, generating magnetic force that pulls down the armature, forcibly moving the diaphragm. The movement of the armature opens the contacts, interrupting the current and causing the coil's magnetic force to disappear. The diaphragm, with its own elasticity and the help of a spring, returns to its original position along with the armature. The contacts close again, allowing current to flow through the coil once more, repeating the above process.
