The Hella 003399801 is a car horn kit that comes as a pack of 2, a low tone horn and high tone horn. This will allow you to spread the sound of the car horn more evenly and create a more powerful and balanced honk. With a loudness of only 118 dB, this Hella car horn is definitely not the loudest in this car horn review.

However, the low tone of 300 Hz and the high tone of 500 Hz produces a piercing sound that will allow you to be heard clearly by other road users. Additionally, this car horn produces a melodious sound which is very pleasing to the ears.

Additionally, due to the small and compact size of this car horn, you will have no problem installing it in tight areas. Therefore, this model is an excellent choice for those who drive a small car and are trying to replace their factory pre-fitted car horn.

Best of all, you can purchase this car horn in other colors to suit your taste. You can even choose the tone as well as a model that comes with or without a relay during purchase. Lastly, installation is incredibly easy and very beginner friendly.

Pros:

  • You get 2 car horns for the price of one

  • Easy to install by absolute beginners

Cons:

  • Not the loudest car horn at 118 dB

Moreover, you can install this electric car horn quite easily and all that is required to make it operational is a 12 V current which is available in most vehicles, including motorcycles.

The Law About Car Horns in the USA

​The Law About Car Horns in the USA

In the USA, the road act and various other federal traffic laws are not specific when it comes to the car horn.

However, each state has their own specific vehicle noise related laws and will need to consult with your states transportation department to make sure if your car horn complies with state laws or not.

In general, road users are allowed to use a car horn that is not unreasonably loud. Additionally, you can safely honk in allowed areas as long as your car horn is factory fitted.

If you are performing a custom job and fitting your vehicle with your own aftermarket car horn, then you must make sure that it is below the maximum decibels allowed by the law. In most cases, this is between 100 dB to 110 dB.

Since most electric car horns sold commercially are more than 110 dB, you need to enquire from either your state’s police superintendent or transportation department to ensure that you can use this car horn safely and legally.

Additionally, some states like California prohibits car horns that exceed 110 dB but still allows you to attach the horn to your vehicle, as long as you do not attach the electrical wires. Any violation of this law and you will have to pay at least $108 in fine.

When it comes to states like Virginia, Texas, and Georgia, the law allows you to connect a car horn that exceeds a tolerable limit as long as it is attached to your car anti-theft system only.

If you do not plan to connect it to your anti-theft system, then you may always install the car horn without connecting it to your electrical wiring just to comply with the law.

In any case, you will have to ask your police superintendent or read the notices of your states’ transportation department to know if your car horn is legal or not.

How to Buy the Best Car Horn

1. Shape and size

In general, the shape and size of the car horn do not matter much if you are planning to put it under the hood. There will be more important factors like the ease of install, loudness, tone, and installation space to take into account.

However, if you are planning to place your car horn in a visible location, like in the front of your RV, then you need to consider its shape for aesthetic reasons.

In this case, it is better to go with a trumpet style car horn since it is made to be fitted in front of vehicles and not under the hood.

Additionally, the size must be appropriate for the size of your vehicle. For example, if you operate an RV, which is a big vehicle, then you can go ahead and retrofit it with a big unit like a train horn.

But if you have a small vehicle, it is ideal to go with a smaller and more discreet car horn.

2. Sound

The sound is mostly the primary reason why people choose to upgrade their car horn to an aftermarket model. The sound of the car horn will mostly depend on the tone of the horn.

The tone is measured in hertz and the higher the hertz, the more high-pitched the car horn will sound. If you want a high pitch car horn, then it is best to go a model that is at least 500 Hz or more.

On the other hand, if you want a deeper car horn sound, it is best to go with a model that is less than 400 Hz. Additionally, many manufacturers ship their car horns in 2 variants, a low tone horn and a high tone horn for tone flexibility.

3. Material

The material of the car horn is an important aspect to consider. This is because the material used in its build construction will dictate how long and durable the car horn will be.

In most cases, the car horn is made from a high-grade ABS plastic that is very durable and long-lasting. Furthermore, it even has good heat resistance and will not melt away when your vehicle is running and heated.

Additionally, some of the best aftermarket car horns are made from stainless steel which means that they have an excellent chrome finish as well as lasting a long time. Of course, a stainless steel car horn will be more expensive than a plastic model.

4. Durability

The durability of the car horn will dictate how long it will last. Indeed, the caller needs to be heavy-duty and durable because this is not a car accessory that is often changed.

Therefore, you need to ensure that your new car horn is made of high-quality materials that will make it durable and long-lasting.

As already stated above, a quality car horn will be made from a corrosion-free material like stainless steel or even ABS plastic. They have good resistance to heat and should last you a long time.

5. Ease of install

In general, the car horn is not very difficult to install. Pay attention to whether or not the manufacturer states anything about the installation process. In any case, all you will have to do is remove your old car horn and replace it with your new one.

As long as you are not installing an air car horn with a compressor, the installation is very easy and even absolute beginners can do this replacement within a matter of minutes.

6. Installation space

You need to assess the installation space and take into account the size of your car horn before installation. Some installation spaces are small so you should purchase a horn of a suitable size so as to fit and replace your OEM car horn.

If you are unsure about what size of electric car horn you need, you can always compare it to your old factory fitted car horn. In general, it is always better to buy a new car horn that is smaller than bigger. This is because a smaller car horn will fit into the installation space much easier than a bigger car horn.

How to Install a Car Horn

Installing an electric car horn could not be easier. Here is a stepwise manner how to proceed.

Step 1 - Locate your car horn

The first step when installing a horn is to first find out where your car manufacturer placed the car horn.

Generally, if you pop open the hood you should easily be able to see it. If not, you can consult your user’s manual or simply ask someone to honk so that you can locate it.

Step 2 - Disconnecting the wires

The car horn is usually connected to a pair of 12 V wires that provides it with electricity. They are rarely soldered and you should find 2 connectors that connected to your car horn.

Simply disconnect the wires so that you can now easily access the car horn. Due to corrosion, you may need to use an anti-rust spray like WD 40 to break the rust before disconnecting.

Step 3 - Install your new car horn

Now that the wires are out of the way, unscrew your old OEM car horn to its support and replace it with your new car horn. You may want to replace the screws as well.

Additionally, many manufacturers make their car horns with a standard base mount for installation so you should not have any problem installing your new car horn using your old installation accessories.

Step 4 - Check everything

Now that you have installed your new car horn, give it a honk to see if it works. If the sound is tiny, then you probably need to replace your car horn fuse as your new car horn may have higher electrical specs than your old one.

There you have it. Installing a new car horn is not very difficult and it can even be done in a matter of minutes. All you need is some patience.

Conclusion

As we have seen, it is possible to install a custom and legal car horn to replace your OEM car horn that came factory fitted with your car. One of the best things about this system is that it is very easy to perform and you can do it in a few minutes.

There is a wide variety of car horns on the market to suit your liking. You may prefer to go with a car horn that has a deep tone or one with a high pitch depending on your personal taste.

Finally, if you have read our car horn review above and still not found a decent model, we recommend you go through it again.
