Very loud!!!
I used these to replace my old horns after one stopped working. They are bigger than the original horns, and they are very loud. If you are trying to be discreet, forget about that! They made me so self conscious that I refused to use the horn much on the day after the installation. These are very powerful and echo when honked. They seem durable. The price was worth it.

They are, in every sense, a thing of automotive glory
I recently purchased a 2025 Subaru Forester, and it came equipped with a horn that could best be described as well this side of anemic. I can’t quite capture the sound it made, but suffice it to say it wouldn’t have disrupted evening prayers in a cloistered nunnery. Since I live so far out in the rural wilderness that one must walk toward town to go hunting, I regularly encounter a veritable horde of wildlife worthy of the fire scene in Bambi. With that said, I need an authoritative horn—something capable of announcing to the denizens of the woods that a rather large, fast-moving object is arriving and possibly not in full control. After browsing through a digital bazaar of countless horns here in the Amazon mercantile, I decided to take a chance on this pair of Hella horns. I’d like to claim that their extensive technical specifications swayed my decision, but that would be a lie of convenience. The truth is, it was their glorious red, candy-like color that spoke to the tiny child within me—the one who shouted, “I must have them!” With my dubious selection process now exposed, I can report that serendipity decided to smile upon me. These little red pancakes were delightfully easy to install, and—by some miracle—Subaru had already provided adaptable mounting points beneath the bonnet of my worthy steed. When I pressed the horn button, I was rewarded with a loud, two-tone, gloriously raucous blast. The child in me grinned a lascivious grin of delight, and I pressed the button again… and again… chasing endorphins like Pavlov’s most self-satisfied dog. Eventually, I stopped—mostly out of concern for my own moral character. That afternoon, taking the Subaru down the open road, I realized these horns were everything I had been looking for. I should have known—being German, they could produce nothing less than a trumpet of Teutonic glory, as though my Subaru were parked at the gates of Valhalla demanding entrance. To be honest, I now find myself inventing reasons to use them. Each blast conjures the sound of a road rally, and I half-expect a co-driver beside me screaming, “Hard right! Straightaway! Hard right again!” at the top of his lungs. They are, in every sense, a thing of automotive glory.

HELLA LOUD
Decided to upgrade my F350 with the HELLA Supertone 12V High Tone/Low Tone Twin Horn Kit, I was going for something that demanded attention. And oh, it does—just not quite in the way I expected. Picture this: a beast of a truck that, when it honks, unleashes a sound you'd swear was a very angry, very loud Volkswagen. My dad can't stop laughing, and honestly, it’s become a bit of a running joke. About the horns themselves. First off, the red protective grill gives them a pretty cool look—if aesthetics are your thing, these don't disappoint. Installation was straightforward enough, not rocket science, but here's the kicker: these horns are LOUD. I mean, really loud. The kind of loud that gets everyone's attention on the road (and possibly a few startled glances, wondering where that sound is coming from). The twin horn setup, offering both high tone and low tone, creates a sound that's undeniably powerful, albeit not the deep, throaty honk you might expect from a truck. Instead, it’s a sharp, penetrating sound that slices through traffic noise with ease. So, would I recommend the HELLA Supertone Horns? Absolutely—if you're looking for something that packs a punch volume-wise and you can appreciate the humor in turning heads with a sound that defies expectations. Just be prepared for some confused looks and a good laugh, especially if your vehicle looks nothing like a Volkswagen

Unmatched Hella Sound
This is my 3rd set of Hella Supertone horns. The first 2 were purchased long ago to upgrade the sound of a Mercedes and Land Rover. They were made in Germany. This set was made in India. Other than buying factory replacement horns for a vehicle whose horn sound you like, buying horns based on an expectation of a certain sound or tone is actually quite difficult. I like the sound of the Supertones, but I knew that before buying them. They really sound like Mercedes Benz horns from the 1970s - early 2000s. If you like that sound, you will certainly like these. Others may find the sound kind of shrill. One thing is for sure: any prolonged blast is impossible to ignore. You will be noticed. You will be heard. These horns are directional, so attention and planning should be made to aim them forward if possible. The enclosed mounting "bracket" is useable only if you are replacing a similar style horn. Please note that you may need to fabricate a custom bracket to mount the horns properly. This is what I needed to do. Also note that these horns are actually quite large and may not fit where thd original horn was mounted. I prefer the slightly smaller 4 inch horn for ease of fitment. These were installed in a 2007 Ford Escape. I had to remove both inside front fender liners and the front bumper cover to access the original horn. Disassenbly and reassembly took over 4 hours. Fabricating mounts and installing all wiring to and from the horns and relay took a few more hours. It was worth it, but it was a full days work. Plan your time accordingly. I must note that you must use the included relay or be certain that your own vehicle has a dedicated 15 amp circuit for the original horn. Most will not. Failure to wire horn as instructed will result in lower volume. This voltage drop accounts for some of the poor reviews of this product. Also, the instructions are very clear only if you are used to reading electrical diagrams. Otherwise, they stink. Hella Relay Wiring Instructions: These instructions are for vehicles where the horn button supplies power to the horn when depressed and the ground is constant. Terminal 85: chassis ground Terminal 86: intermittent positive lead FROM steering wheel horn button TO original horn Terminal 87: output TO new horns Terminal 30: 12v constant with fuse 15A Please Let me know if this review helps. Good luck.

LOUD
LOUD AF and quite a distinctive sound that is sure to grab anyone's attention. Personally, I would love it louder, because I don't give AF about other people.

it's a horn.
As expected due to the size They are louder than stock car horns. The sound seem better suited for a car doesn't really have that "get out of my way I'm a truck" sound.

Years Later
Years later and they still work! Great quality, I installed them on a 2017 Honda Accord V6 Touring and it was practically Plug and Play, so thank you!

Great quality horns, nice and loud
Loud. That is what these are. I've installed these on my Hyundai Santa Fe as the stock horn on that car is nothing but embarrassing. I managed to replace them with these Hella horns without having to remove the bumper. It can be done by just removing the headlights. It is very tight though! Using some spade connectors, I created a wire to go from the horns to the existing wiring, no need to use the relay that comes with the horns in my case which helped make it even easier. I'm no mechanic by any stretch of the imagination. Really pleased with these although the new sound is different to what you might expect. All I cared for what the loudness and I got it.

HELLA weiß eben wie es geht…!
Habe mir beide Hupen eingebaut und was soll ich noch großes sagen als: Mega Hupen!! Klar, sie klingen etwas anders als die Serienhupe, aber sind deutlich lauter und sehen obendrein auch noch optisch sehr gut aus! Wenn man sie hinter seinem Grill platziert, wo sie gut zu sehen sind. Würde sie jederzeit weiter empfehlen!
