The car Klaxon sound—that loud, unmistakable “oogah!”—was one of the earliest horn tones used on automobiles. It was designed to cut through traffic noise and grab attention, and it quickly became a staple of early 20th-century vehicles. Today, that same nostalgic sound is still turning heads, whether it's on a restored classic or used as a custom touch on a modern build.
In this article, we’ll break down where the Klaxon horn came from, how it works, why the sound became so iconic, and how you can get the same effect for your own vehicle today. If you’ve ever heard that vintage “oogah” and wanted it on your ride, we’ll show you exactly how to do it.
HISTORY OF KLAXON HORNS
The Klaxon horn was invented in the early 1900s by Miller Reese Hutchison, an American electrical engineer. The name “Klaxon” comes from the Greek word klazō, meaning “to shriek,” which perfectly describes the sharp, mechanical sound it makes. That loud, vibrating “oogah” noise became one of the first standard warning sounds used on early automobiles.
By the 1910s and 1920s, Klaxon horns were installed on everything from Model Ts to luxury cars. At the time, roads were still shared with horses and pedestrians, so cars needed something loud and distinct to get noticed. The Klaxon horn delivered just that—and did it better than any bell or whistle.
Over time, as vehicles and traffic laws evolved, more modern horn sounds took over. But the classic car Klaxon sound never disappeared. It became a symbol of the early days of motoring and a go-to choice for anyone wanting to add some vintage character to their vehicle.
HOW KLAXON HORNS WORK
Traditional Klaxon horns use a small electric motor to spin a notched metal disk, which rapidly opens and closes contacts to create a pulsing electric signal. That signal powers a diaphragm that vibrates against a resonator, making the signature “oogah” sound. It’s a simple system, but the mechanical design gives it a raw, loud tone that’s hard to miss.
Older versions had fully mechanical internals, usually housed in a metal casing. They were loud by design—built to cut through early traffic noise and grab attention. You could hear one coming from a block away.
Modern versions, like the ones we carry, use updated electronics to recreate the same sound without all the moving parts. That makes them easier to install, more reliable, and better suited for today’s 12V vehicle systems. They still honk with that same unmistakable tone, just with less hassle.
COMMON QUESTIONS
- Why is it Called a Klaxon?
The name "Klaxon" is derived from the Greek word "klazo," which means "to shriek." This name was chosen to reflect the horn's loud and piercing sound, which was essential for early automobiles to alert pedestrians and other drivers.
- What is the English Name for Klaxon?
The English name for Klaxon is simply "Klaxon horn." It is often referred to as an "oogah horn" due to the distinctive sound it produces.
- What is the Difference Between a Siren and a Klaxon?
A siren produces a continuous or oscillating sound, often used in emergency vehicles for warnings. A Klaxon, on the other hand, produces a sharp, distinctive "oogah" sound, primarily used in vintage cars or for nostalgic purposes. Both are designed to grab attention, but their sounds and applications differ significantly.
- Are Ahooga Horns Legal?
In most regions, Ahooga horns (a common nickname for Klaxon horns) are legal for use in vintage or custom vehicles. However, local noise ordinances and road safety laws may restrict their use in certain areas. Always check your local regulations before installation.
- What Sound Does a Klaxon Make?
A Klaxon horn is famous for its "oogah" sound, a sharp and loud noise that is both nostalgic and attention-grabbing. This sound is created by the rapid movement of the diaphragm in traditional Klaxon horns or through electronic replication in modern versions.
- Is it a Horn or Claxon?
The correct term is "Klaxon," not "Claxon." It specifically refers to the brand of horns known for their unique "oogah" sound. Over time, "Klaxon" has become a generic term for any horn that produces this type of sound.
- What is a Synonym for the Word Klaxon?
A common synonym for Klaxon is "oogah horn." Other terms that might be used interchangeably include "vintage car horn" or "classic car horn," though these do not specifically refer to the Klaxon brand.
MODERN USES
Klaxon horns might have started on early cars, but they’re still a favorite today. A lot of vintage car owners use them to stay period-correct, while custom builders add them for that old-school personality. Nothing sounds like an “oogah” horn—it’s loud, funny, and grabs attention in a way no regular car horn can.
Outside of cars, people use them on parade floats, golf carts, rat rods, and even boats. The sound cuts through crowds, so they’re also popular at events, fairs, and promotions. We’ve even had customers install them just for laughs in a workshop or garage. Anywhere you want a horn that makes people turn and smile (or jump), a Klaxon delivers.
Even though tech has changed, the appeal hasn’t. It’s still that same sharp, mechanical honk that people recognize instantly.
