Semi Truck Horns

Since a semi truck is a heavy vehicle, the amount of noise it makes while driving is also huge. If you want to be heard and let others know of your presence, you need to equip your big rig with a powerful horn.

In our online store, we’ve gathered an abundant selection of top-notch semi truck horns from some of the most trusted manufacturers in the industry.

When it comes to shopping for a semi truck horn, it’s important to consider several factors so you can choose the one that’s right for your needs. First of all, you have to be sure that the noise a horn produces is high enough to allow you to drive anywhere with peace of mind that everybody can hear you clearly. In this case, an air horn is the best option. Originally used on ships and locomotives, air horns are capable of creating a very loud noise by pushing the compressed air through a diaphragm or reed. As a result, the compressed air in the reed or diaphragm starts vibrating, creating a sound wave.

The powerful sound is not the only benefit an air horn can give you. Air horns usually come with trumpets attached to an air chamber with a diaphragm or reed. These trumpets not only amplify the sound energy from the diaphragm or reed so that you can enjoy all the noise you want, but are also the perfect way to customize the exterior of your big rig and make it look truly unique. Made either from metal or plastic and available in various finishes including powder coated and chrome, they are proven to give your big rig that unique customized look you’ve been craving for. But don’t forget to make sure that trumpets are durable enough to withstand all weather conditions.

Many drivers prefer to equip their semi truck with both air horn and electric horn. The latter is less loud which allows you to drive safely in highly populated areas without bothering other road users. A typical electric horn has a spring steel diaphragm, an electromagnet, a switch, and a housing that acts like a megaphone amplifying the sound. The entire device functions using the principles of electromagnetism. When you press the button applying current to the electromagnet, the diaphragm starts moving towards the magnet, and when it finally reaches its maximum point, the current is instantly interrupted to allow the diaphragm to spring back to its original position. Once it happens, the current is restored and the process is repeated. The constant back and forth movement of the diaphragm is what helps create the desired sound.

If your electric horn is faulty or broken, you will put your safety and the safety of other road users at risk. So it’s recommended to replace it as soon as possible.
