Truck air horns make an incredibly loud noise. If you’ve ever heard a semi-truck blaring its horn, that is what an air horn sounds like. These large horns signal warnings to other drivers that something is wrong. Of course, we’re all pretty familiar with the impatience of people and how quickly some might push their horns to signal others to get moving. Here’s some more information about truck air horns you might find interesting.
Do truck air horns require power to operate?
Certainly, you could use a handheld model to signal others, but that will get old really quickly. Air horns used on vehicles require a power source to work. The Drive tells us these models typically connect to a 12V battery using an outlet and wiring harness. Power for these horns comes directly from the truck’s battery, making it easy to wire and achieve the desired connection.
Air horns that are designed for vehicles are made to activate when the steering wheel button is pushed. This makes these horns easy to use. Buses and semi-trucks use electric and pneumatic air horns activated using a switch on the dashboard.

Some people even take air horns to sporting events as part of their traditional cheering activity.

How much air pressure is required?
Smaller air horns require as little as 100 psi of air pressure to work effectively, while larger models could use as much as 200 psi. The pressure required for an air horn varies from model to model. For the best installation, consult the manufacturer’s guide and use the right compressor.
