2. Kleinn Air Horns 102-1 Black Dual Air Horn

Why we like it: These horns stand out with their longer design, which is mainly suitable for a truck-like deep sound.

Editor’s rating:

Design Features
Not all truck horns are the same. Some of them offer a higher pitch sound while others offer a lower deep sound. The Kleinn Air Horns are part of those with a deep sound. This is mainly due to its design. Made with longer trumpets, the air horns are now able to offer a distinct sound. But the design of the air horn is different as well. Unlike many single-trumpet air horns, Kleinn decided to use double trumpets for a more distinct sound.

But the convenient design does not end here. The trumpets also come with an all-metal body. This makes them more durable. But the metal materials are also recommended for their truer sound, even if it is not as loud as some of the other air horns on the market.

Convenient Features
Kleinn’s Air Horns are made with double trumpets which produce a maximum sound level of 153db with a powerful compressor. Apart from its unusually loud noise, the trumpets also offer distinct deep sound due to their metal construction.

But since the air horns are made from metal, they also need to be protected against corrosion. This is why the manufacturer used Black XCR 2 copper coating to keep the air horns protected. Since the air horns are not that long at 16.7 inches, they can be fitted in various parts of the truck. Depending on their location, they can come with louder sounds than those of an ambulance or of a fire truck. Of course, in order for the air to go through the trumpets, an onboard air system is required as well. A 150PSI air system is advisable and it is sold separately. It works well with the included Vortex 4-12Volt solenoid.

Verdict
With a loud performance, the deep air horns are a top choice for truckers who want a product louder than an ambulance air horn.

Pros
  • High 153db noise capacity
  • Designed with an all-metal construction
  • Included 4-12 electronic solenoid
  • Coated with corrosion resistant material
Cons
  • Onboard air system sold separately

It even comes with an all-black design which can blend in with the car’s parts well. The compressor has a distinct red polished look which can give the truck a more sophisticated look. But as most truckers notice, the air horns come with two trumpets. So even if they are not as long as other trumpets, they still need enough width to be installed under the hood.

Convenient Features

Apart from the convenience of the pack, it also comes with parts that have a distinct look and which can make the truck even more attractive. The air horn itself is designed with 4 trumpets. The longest trumpet comes with a length of 13.75in. Since the air compressor needs to be installed with it, truckers also need to know it is not significantly larger than the trumpets. At a length of just above 15 inches, the air compressor needs to be installed in dry locations around the truck.

Convenient Features
The most convenient aspect of the air horns comes with their loud sound. The sound is not particularly low, but rather on the higher side of mid tones. But it still comes with a loud noise based on the powerful performance of the 110PSI air compressor. There are a few ways in which the air horn and the compressor can be installed for maximum efficiency.

For the sake of shorter installation time, it would be ideal if the air horn would be installed next to the engine, under the hood. This is not possible in all cases, but the manufacturer still advises users to install the air compressor in a safe and dry area of the truck.

Installed under the hood, under the truck or in any other location, the air horns are loud and they are up for the task.

Furthermore, the air horns are easy to install and they can represent an alternative for drivers unwilling to spend too much time with additional air systems.

Convenient Features
The most convenient capacity of the air horns is their sound level. At 148db, they have comparable performance with some of the best products in their class.

9. VaygWay 150db Air Horn

Why we like it: This compact air horn is one of the economical options and it still manages to offer a loud sound.

Editor’s rating:

Design Features

It ships with a small compressor which powers the single trumpet of the air horn. Without this compressor, the trumpet would not be able to reach its full sound potential. A relay, a hose and basic mounting hardware such as a support and screws are added to the pack as well. Designed with a polished finish, the air horn is among the durable designs in its class. It represents one of the more suitable options for those with limited space for an extra horn.

Convenient Features
With a 150db loud sound, the air horn is unmistakable. It even comes with a single trumpet, which is very rare for this type of volume. But even with this single trumpet design, it is still reliable and it can even save space if mounted under the hood. But some truckers will immediately mount it on the cabin so that it becomes visible. Since it is made with a high standard of durability, it will not be impacted by changing temperatures.

But at the same time, the air horn is one of the most economical options for truckers. Apart from its affordable price, it also uses a standard 12V power outlet to blow the horn. Unlike air horns with two trumpets and two compressors, it actually places less pressure on the battery.

Verdict
This economical design is suitable for truckers driving in cold weather, where the truck’s battery has to work extra hard.

Pros
  • Made with a single trumpet
  • Includes a small compressor

Guide to Buying the Best Air Horns for Trucks

Choosing the best air horns for trucks is not complicated. Most users can do so on their own, without any specialist knowledge. Some of the air horns on the market include all the required hardware needed for installation while others only come with trumpets and a few other accessories such as an air hose. But where does a trucker start looking for the best air horns?

Decibels and maximum sound level
Obviously, decibels are important. They can make the difference in the distance it takes other traffic participants to notice an oncoming truck. But having too many decibels is actually dangerous. This is why a few of the best air horns of the moment are actually limited to 150db. Some of them are even made with a lower sound volume, but this doesn’t necessarily make them any better. In most cases, it is clear that users have the capacity to choose both a high volume system and quality acoustics.

Design and fit
The design of the air horns is very different. Form a single trumpet to 5 trumpets, there are endless possibilities. But for most users, it can also be a clear sign that the design of the air horns should actually match their truck’s possibilities. This is why it’s so important to find the right design from the start. Judging by a few experiences, some truckers are only able to mount their air horns under the truck while others prefer them somewhere on the truck.

But there are cases where truckers actually change the air horns from vehicle to vehicle. For example, if they are not driving during the winter months, some truckers move the air horns on their personal vehicles and in this case, a compact design might be a better choice. It seems that the design of the air horns is more important than many new users might think of.

Finishing and durability
Should truckers choose metal or plastic air horns? The debate is still continuing and each user has personal preferences. But for many users, it is clear that both options can work well. Those with an ear for detail know that there is a difference in the two materials. Metal usually favors deep sound while plastic works with mid-high notes. But there are plenty of exceptions and metal construction is not a guarantee for any sound, unless properly crafted.

Parts and extras
Extras can include air compressors. Some air horns come with a single air compressor while others come with two. Some of the loudest air horns actually come with no air compressor and they are based on the air from an onboard air system. But even in this case, they can come with the right durable hose for connectivity purposes. However, it is also important to consider the right instructions manual along these extras, especially if truckers are installing the air horns themselves.

Warranty and other policies
All air horns should be covered by a minimum warranty policy. It is typical for this warranty period to cover up to 1 year of possible manufacturing defects. But a number of manufacturers also offer other incentives such as lifetime customer support. So all the questions truckers might have can be quickly answered in the future.

Using air horns safely
Above all characteristics, truck air horns should be used responsibly. Apart from being up to date with state and local regulation, trucker should also not abuse air horns, even when in areas where they are allowed. This is why they should only sound the horns when truly needed. Sounding them too much or just for fun can actually scare traffic participants. This is why common senses are also needed alongside the very strict regulation in this area. Some of this regulation refers to all morning. Areas in the vicinity of hospitals or schools are particularly known for banning horning.

Final considerations

Some of the best air horns for trucks are able to be quickly installed. Among other characteristics, it’s worth noting people are actually relying on them to work in emergency situations. Proper testing should be carried out after installation in an area where sounding the horn is legal.
Since there are many types of air horns, truckers should choose a product which is easy to install and which can also be used in different conditions, especially if driving across the country. It is more likely to encounter changing weather conditions on long routes and this is why a durable air horn is needed, especially when mounted on the truck or under the truck. Luckily, such options are available as seen above. In the end, it might only be a matter of choice and design compatibility as some truckers may struggle to find the right place to install the air horns. However, reading the full instructions manual is the first installation step, regardless of the location of the future air horn on the truck.
