The OEM 12V Electric Horn 3721920Q15 is a direct-fit replacement sound signal designed for JAC N56 light trucks. Manufactured under the FIVE LION brand, this high-tone horn converts electrical current into a clear, audible warning signal for safe vehicle operation.
Working Principle: The horn contains an electromagnet and a diaphragm. When the horn button is pressed, current flows through the electromagnet, pulling the diaphragm and opening a contact. The contact then re-closes, creating a rapid vibration that produces sound. The horn must deliver a consistent, loud tone to meet vehicle safety requirements.
