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

Want to me seen & heard? These are LOUD!!!
I now have 3 sets of these horns installed on my vehicles. I will soon be running 2 sets on one car as it is my personal show car and if Im driving it...whoever needs to be "alerted" will hear me! I am a car enthusiast as a hobby. I am one of those people who cant leave anything stock. Weather its a car, truck, SUV, call phones, laptop, etc...I have to modify it. And lets face it...stock factory car horns usually suck! In many cases it is embarrassing! Installation can be difficult depending on the car simply because these are larger than the factory horns and mounting them can be time consuming. Even knowing how to wire them in it still takes an afternoon to do a proper, clean install. Sometimes, to do a real clean install will take a day. These horns are NOT plug-n-play. They do require wiring and hardware not supplied. As everyones setup will be different, so it is impossible to include these parts in the kit. Once installed these horns work exactly as described....LOUD! Once you see the look of terror from some random driver the ends up with an ear-full of horn through there open drivers window, you will know the cost of these was justified. If you choose to hook these up to your alarm system as well, be ready for a very loud and almost obnoxious sound. These work great when hooked up to the alarm siren, even overpowering the siren in most cases. These are the best sounding horns out there. They are loud, sound great and perform every time. In no way are these cheap horns in terms of quality or performance. I will use these on every car I own and recommend them to everyone who asks. UPDATE: On my factory Nissan keyless entry, the horns sound funky and wimpy when locking the vehicle due to the short burst and most likely low voltage singal sent to the horns for the keyless system. It sounds aathmatic. UPDATE #2: The low pitch horn died on my wifes car. It now sounds funky as only the high pitch works. A little disappointed as these only lasted about 5 years for me now.

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.

I’m using Nissan Pathfinder 2018 on OEM wiring and its working better than the OEM horns.

独特ないい音が鳴ります。 PIAAなど他メーカーのホーンとかぶりたくない人におすすめ。

While this is a good useful item when new..the one that came looks like it has been in storage for a looooooooong time. Box colors were kind of faded and crinkled caused by humidity and packaging box containing the items looks like it been playing football..lots of crumpled corners and banged on!..very discouraging and stressful to see an item you paid for with honest earned money looks like that. At any rate, the horn is working alright but not as solid in sound as my previous new one.
