7 Best Bull Horns For Your Truck

Before we get going with the horns, let us take a moment to clarify the distinctions between air horns and bull horns. The main difference between air horns and bull horns is that air horns are limited to performing the loud horn function. In contrast, the bull horn has that horn function and the ability to translate vocal communication with the use of a handheld receiver/microphone.

When technical or installation help is required, always consult with either a licensed mechanic or specialist to ensure that your installation is handled correctly. ALWAYS be sure your vehicle is code compliant with local noise codes. All relevant information should be readily available through local motor vehicle authorities designated webpages.

How Does A Bull Horn Work?

The bull horn operates similarly to a megaphone or air horn, and that is by channeling sounds waves made and directs them towards objects at an amplified decibel range/volume. This principle of the science has remained relatively unchanged, and therefore the overall horn design has gone relatively unchanged.

Today, most models and designs utilize microphones to capture the sound waves, which is the most significant difference in designs now versus designs of old. These waves are then processed through an amplifier that will use the electrical circuitry connected to the battery to increase the audio output, which can then be adjusted based on the volume desired. 

Can You Make Your Horn Louder? 

If you absolutely need your horn to be louder, then there are two options available for you to consider. You can either 1) manually adjust the horn’s volume from a dial/knob found on the horn itself or 2) outright replace your existing horn. For whichever route you opt to go, each method has been labeled and has had its process listed out step-by-step below.

Option 1:

Adjust Horn Volume

  1. Disconnect Car Battery
  2. Locate Vehicle’s Horn
    • You can refer to the operator’s manual. Still, if it is not readily available, the horn should be located in one of three common areas: 1) next to the battery, 2) near the wheel well, or 3) connected to the front grille of your vehicle. They are typically cylindrical in shape.
  3. Unfasten Horn Bracket
    • With the horn removed from the bracket, a dial becomes will visible and newly accessible to adjust up or down.
  4. Pinpoint/Adjust Volume Dial
    • Make your desired adjustments to increase or decrease volume.
  5. Refasten Horn To Bracket
  6. Reconnect Ground Wiring To Battery
    • At this point, you can test the volume to verify it is at a sufficient level to grab the attention of nearby motorists and pedestrians.

Option 2:

Replace Horn

  1. Disconnect Car Battery
  2. Locate Vehicle’s Horn
    • You can refer to the operator’s manual. Still, in the event it is not readily available, the horn should be located in one of three common areas: 1) next to the battery, 2) near the wheel well, or 3) connected to the front grille of your vehicle. They are typically cylindrical in shape.
  3. Unfasten Horn Bracket
  4. Disconnect Old Horn/Install New Horn*
    • *If the new horn being installed does not match the mounting hardware, you will have to either swap out with new mounting hardware or identify an alternate location to install the horn. 
  5. Fasten Horn To Bracket
    • If the horn is a like-for-like swap, it should be a quick change out, but if you upgrade the hardware, then be sure to follow all instructions carefully to ensure proper functioning is achieved.
  6. Connect Ground Wiring To Battery
  7. Re-Establish Horn Power Supply
  8. Reconnect Ground Wiring To Battery
    • At this point, you can test the volume to verify it is at a sufficient level to grab the attention of nearby motorists and pedestrians.

How Far Away Can A Horn Be Heard?

Depending on the decibels, a horn can be heard from relatively far away. Your standard car/vehicle horn may be audible up to 200+ feet away, while more powerful horns like the bull horn or air horn can be heard from up to 8 miles away.

What Is The Loudest Horn You Can Buy?

The loudest horns legally available can achieve volumes of up to 150 decibels. Anything higher than the 150-decibel range has been shown to cause immediate disorientation and, more significantly, hearing damage. Air horns are the loudest horns that can be bought legally without special licensing or permits required.

In Closing

If you feel your truck would benefit from the addition of a bull horn, you can rest assured there are many high-quality options out there and available for your selection. If you pull the trigger and get the bigger horn, you can be sure you will always be able to be heard wherever you are. Until the next time we meet, keep safe, keep smart and keep savvy on the open roads. Honk! Honk!
