How to Choose the Best Horns & Accessories

Types of Horns

  • Electric Horns: These are the most common type, operating on a single-tone or dual-tone principle. They are generally easy to install and offer a significant upgrade over stock horns in terms of volume and tone.
  • Air Horns: Known for their extremely loud and distinctive sound, air horns require a compressor and air tank. They are popular for trucks, RVs, and specialty vehicles where maximum audibility is desired.
  • Replacement Horns: If your existing horn has failed or you're looking for a more robust sound, replacement horns offer a direct upgrade. Consider the mounting location and power requirements when selecting.

Key Features to Consider

  • Sound Level (Decibels): Higher decibel ratings mean a louder horn, crucial for larger vehicles or noisy environments. Ensure the decibel level complies with local regulations.
  • Tone: Horns come in various tones, from standard beeps to deep, resonant blasts. Choose a tone that is both attention-grabbing and suitable for your vehicle type.
  • Durability and Weather Resistance: Look for horns constructed from robust materials designed to withstand various weather conditions, ensuring longevity and reliable performance.
  • Voltage Compatibility: Most horns operate on a 12V system, but always confirm compatibility with your vehicle's electrical system.

Installation and Accessories

  • Wiring Harnesses: For air horns or more powerful electric horns, a dedicated wiring harness may be necessary to handle the increased electrical load and ensure proper function.
  • Mounting Brackets: Ensure you have appropriate mounting brackets for your chosen horn. Some horns come with universal brackets, while others may require specific mounts.
  • Relays: Relays are often used to protect the horn switch and wiring by allowing a low-current switch to control a high-current circuit.

Frequently Asked Questions

What is the difference between a single-tone and a dual-tone horn?
A single-tone horn emits one distinct pitch, while a dual-tone horn produces two different pitches simultaneously. Dual-tone horns are often louder and can be more effective at capturing attention.
Can I replace my car's factory horn with a louder one?
Yes, in most cases you can replace your factory horn with a louder aftermarket option. However, it's important to check local laws regarding maximum allowable decibel levels for vehicle horns.
Do air horns require a special electrical system?
Air horns typically require a compressor to generate the sound, which draws more power than a standard electric horn. While they usually run on a 12V system, ensure your vehicle's alternator and battery can support the additional load.
Are there legal restrictions on horn loudness?
Yes, most jurisdictions have regulations limiting the maximum decibel level a vehicle horn can produce. It is advisable to research and comply with these regulations in your area to avoid fines.
What accessories are needed for installing a new horn?
Depending on the type of horn, you might need a wiring harness, relay, and appropriate mounting brackets. Always check the product's specifications to see what is included and what additional components might be required for installation.
