HELLA 003399801 Supertone 12V High Tone/Low Tone Twin Horn Kit with Red Protective Grill, 2 Horns

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.

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

These Horns were extra horn EH! Great sound and my client loved them.

I went through several sets of "snail" twin tones on my motorcycle... they never last and fail unexpectedly which could be dangerous. I thought I would try these Hellas as a last resort. I like that they are LOUD and seem well built. What I'm not so fond of is the sound; its almost like you're honking in a foreign language. I honestly think some people might hear these and not have the same instant recognition and reaction they would have to more common horn sounds in America. Think of the sound you hear when people are warned out of the road by approaching rally cars, or as another reviewer put it, an extremely angry Volkswagon. Its just weird. I hope people know what it means when the time comes, or will they try to guess how many clowns can ride my bike at the same time.

I'm writing mainly to clarify the electrical current requirements of these horns. They are rated at 66 W each, for a total of 132 W. In a 12 V circuit, that means they will draw 132/12 = 11 amperes. That's Ohm's Law. My car, a very common 2000 Honda Accord, has a horn relay as part of the stock wiring. The horn circuit is fused for 20 amperes. So the stock wiring will operate these horns with a comfortable 9 ampere margin of safety. And they work just fine, I'm very happy with them. But my point is, don't take it for granted that you MUST install a horn relay and new wiring, even though everyone on YouTube and here tells you that. Your car may well be able to handle these horns with the stock wiring. Do a little research and check your car out. You may save yourself a lot of work. And one other thing after reading some of the other reviews. If you think these horns don't work, or they're not loud enough, you must have installed them wrong! Or you need to see an ear doctor. And don't take the nut off the back of the horn! You'll let all the loud out. Road hogs beware! One other note about installing the horns. On my car, it's surprising how easy it is to remove and replace the front grill and bumper. This makes it WAY easier to install the horns without cutting your hands reaching around all the sheet metal brackets and things behind the grill. Really, it only takes five minutes to get it off. So check it out on your car!

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.
