You will find truck air horns on a wide variety of vehicles today ranging from large trucks that barrel along the highway to personal cars and SUVs. While they were once intended to be used as a warning device in the same manner as any other horn, the number of people who have installed them on just about any type of vehicle you can think of. There are so many reasons for installing this type of horn on a vehicle there are different styles of horn on the market. Even the railroad made use of truck air horns when the change from steam locomotives with their steam whistles gave way to the modern diesel locomotive. The diesel had no way to produce steam, but they all used compressed air to operate many systems, including their brakes. This meant that there was plenty of air available to power the horns. In addition, air horns are loud enough to serve as a warning at railroad crossings, even in today's congested traffic. 

Train horns may have started out as truck horns, but today they have been modified not only to sound louder, but also to have a different tone and make it much easier to identify the sound as that of a train or truck for safety reasons. This came about after a nasty accident where a train was mistaken for a truck and the need for a horn with a more unique sound arose. At the same time, if you live near train tracks it would not be wise to install a train horn on your vehicle. Most truck air horns consist of at least two actual horns that are actuated simultaneously by pulling a chain or rope inside the cab. The air for the horns is drawn from the same air reservoir that supplies air for the tractor and trailer brakes. This way, as long as you have air for the rest of your truck, you'll have more than enough for the horns. 

For those wishing to install truck air horns in their personal vehicle you can find sets that have up to four horns and create sounds as loud as 152 decibels, which is as loud as the standard train horns in use today. Since your vehicle probably does not have its own air compressor on board these horns come with their own compressor and everything you are going to need to install your new horns and start blasting everyone's ears.
