What to know about the Horn Relay:
The horn relay attaches a low power circuit to an electromagnet, which operates a mechanical switch. That switch either opens or closes a circuit that carries a higher power, which causes the horn to sound. There is a low power circuit running to your car’s steering wheel, and when it is put on, the horn sounds. When you release the horn button, the low power circuit is opened and the power level of the relay drops, silencing the horn.
Facts to Note:
You are required by law to have a functioning horn in your car.
