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

Easy to install to stock system. Bolt on and plug in. Great look too!

Got a Genesis Coupe R-Spec and the OEM horn has the balls of a flea. Honestly, sounds like a VW horn in the 70's. Terrible. Got these along with harness adapters they work perfectly! LOUD AND PROUD! No more embarrassment at the crap horn. HELLA RULES!

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

I drive a small sports coupe with a wimpy horn which often gets overlooked/cut off in traffic. I installed these with the included relay and let me tell you they get people's attention. I did a lot of research on these so with that the installation/wiring was relatively straight forward and simple. The included diagram is a little confusing, so if you're like me with limited electrical experience you may want to fall back on an online tutorial (there are tons of them). Installing these requires you to remove your OEM horn(s) and I also had to cut one OEM horn connector to splice into the positive (+) signal wire. That is the only modification required to the vehicle itself but it should be mentioned. They function great, have a great appearance and are loud as heck. Some people expect a deep tone but these are pretty "sharp" and somewhat high pitched, but it's an ideal "alarming" tone.4 stars because they are packed rather crudely. The box is thin and there was no packing material what-so-ever inside, only a small thin flap of cardboard separating the two horns. Because of that mine were able to knock into each other in shipment resulting in some very small imperfections and scratches in the red grill paint. You have to be very close to see it but I expect better packing for the price and a company who has been making these for quite a while. My buddy ordered Sharptones and his horns at least came in separate plastic baggies, mine had no such luxury.

The HELLA Supertone Twin Horn Kit is a game-changer for my vehicle. The high tone and low tone horns produce an incredibly loud and clear sound, making sure I’m heard on the road. Installation was easy, and the red protective grill adds a nice touch of style. These horns are perfect for anyone looking to upgrade their vehicle’s horn system with powerful sound and reliability. Highly recommend if you want to make a statement while driving!

Installed this horn kit in a 2000 Toyota Corolla. After that no one cut me off again and always got out of my way.

I own a 2011 Mazda Miata. It had the factory single unit horn. Its sound was is wimpy... like a cartoon bird that runs fast to escape a coyote. But not loud enough to let large pestering vehicles know to back off. Installation in the Miata took some time (but helped by viewing online how-to videos). When I put the Miata on the road again in the spring, the big bullies on the road know I'm there!
