generally draw about 5.5 – 6 amps each.
Does a relay make a horn louder?
To provide the most power, and thus get the most noise, you can wire a relay to power your horn. The relay uses a small amount of power (the original switch circuit) to turn on and off a bigger amount of power (the new heavier wire) to the horn.
Does horn work without battery?
The horn takes power from car battery only. If your battery has enough juice to start your car but not operate your electrically powered horn, you either have a bad horn or there is some type of high resistance in the electrical circuit that activates the horn.
Why does my horn not work?
Car horns sit up front where they’re exposed to rain and road chemicals. But an inoperative horn can also be caused by a bad horn switch in your steering wheel, a broken “clock spring” under the steering wheel, a bum horn relay, a broken wire or a corroded ground. Here’s how to check the most likely suspects.

Can you put a car horn on a motorcycle?
Motorcycles usually have pretty feeble little horns. I have seen car horns that weren’t much better. Most cars have larger, more powerful horns that draw more current. Often when adding a stronger horn it’s advisable to wire in a dedicated power line and connect it and the stock horn wiring to a relay.
Where is the horn on a motorcycle?
The horn button on a motorcycle is usually located next to the left handgrip.
What is a horn relay switch?
The horn relay switches a large current to the horns at a signal from the low-current horn button in the steering wheel. It’s a simple, inexpensive single-pole single-throw (SPST) relay, packaged in a small metal or plastic box with five spade-lug connectors.
How does air horn work?
Air horns work by using pressurized air to vibrate a diaphragm located within a compression chamber. As those sound waves pass from the narrow horn throat to the wide, flared-out horn mouth, they’re amplified. The Kleinn Sealed Air Compressor. Air horn setups usually contain multiple horn pieces that emit sound.
