A car horn is an often overlooked but necessary accessory for your vehicle. Most states require vehicles to have working horns. but choosing the right one can be challenging. You want one that other drivers and pedestrians can hear, but you don't want it to be annoying. The type of sound and tone it emits is very important. Our buying guide will help you find the best car horn for your car or truck.

  • Best Overall
    HELLA Supertone 12V High Tone / Low Tone Twin Horn Kit

    These universal horns are for the performance-driven driver and provide a high level of safety combined with great design and quality. Kit includes one high-tone supertone horn and one low-tone supertone horn.


    These horns are extremely loud and are hard for people to ignore. Installation is straightforward, they're really well made, and they are very high quality.


    The sound may be too shrill. The horns are large and may not fit where your original horn was mounted, and they may use more wattage than your stock horn.

  • Best Value
    HELLA Black 77mm 12V BX Disc Horn Kit

    These universal-fit, ultra-durable disc horns offer a lot of quality at a low price. The kit includes one high-tone 420 Hz horn and one low-tone 350 Hz horn.


    This is a loud and solid-sounding horn. It is louder and sharper than your stock horn, and it's easy to install. It gets people's attention without being deafening.


    This horn is not compatible with all vehicles even though the description says the fit is universal. The high-pitched sound it emits may not be to your liking.

  • Honorable Mention
    Super Loud Marco Tornado Compact Air Horn for ALL 12V Vehicles

    The Tornado horn has a noise level of 150/151 decibels and includes two harmonized tones. It's rigorously tested before leaving the factory and comes with a two-year limited warranty.


    This horn is much louder and much more attention-grabbing than an OEM horn. Installation is simple, and it sounds good with a nice dual-tone.


    It's fairly heavy, and you might need to install a relay if your fuse is not strong enough. Also, the instructions are not very clear.

  • If you don't know what size horn you need, select one that's a bit smaller than the original one that came with your car. It will be easier to install than one that is bigger and may require modification.
  • Be aware that honking your horn can be startling to other drivers or pedestrians. If possible, slow down or stop instead of honking your horn because that may be safer in certain situations.
  • If you aggressively sound the horn when you're driving in traffic or do so really early in the morning or late at night, you may be fined.


Q: When is it okay to use my car horn?

A: You can use your horn when it's necessary to promote safe driving practices. For example, hit the horn if a person tries to turn in front of you, and you want to avoid a collision.

Q: When shouldn’t I use my car horn?

A: Do not honk your horn to make a driver or bicyclist go faster. Do not honk your horn to alert a driver that they made a mistake, because this may make them mad and eager to retaliate. Don't honk it simply because you're upset.

Q: Are loud car horns legal?

A: Some states have laws that limit the volume of acceptable decibels. Typically, car horns on passenger vehicles are rated between 100 and 150 decibels.
