HELLA H31000001 Sharptone 12V High Tone/Low Tone Twin Horn Kit with Yellow Protective Grill, Includes Relay, 2 Horns

Poor sound quality i give this product in one month before in many time in repair very poor bad product

Great horns but the packaging needs to actually protect them.

Pas super évident à installer quand comme moi on n'y connait que très très peu en électricité. Montés sur une 350z, j'ai l'impression que le niveau sonore est seulement un peu plus élevé que les trompettes d'origine (malgré l'installation du relais). Elles respirent cependant la qualité et sont assez esthétiques !

Muy buen tono, pero algo complicado en instalar, no tiene un manual, cómpralo solo si eres ya diestro en instalar estos, o llevarlo a un técnico para su instalación

LOUD!!!!! Fantastic horn and easy to install on my Toyota Highlander. It literally took me 15 minutes from start to finish, and I did it the right way. Toyota makes it easy to get to your horns. In less than two minutes I was unbolting and unplugging the old horns. I was thrown at first by the positive and negative posts, seeing Toyota just has one simple plug, but I plugged the Toyota plug into one side and then ran a 12 gage wire from the other post to ground with the bolt that attached the horn to the car frame. No need for the relay. I wrapped all connections with electrical tape and repeated the same process on the other side. Before buttoning up the car again I tested out the horns. LOUD!!!! Interestingly they are ear piercingly loud when you are in front of the car, but not loud at all from inside the vehicle. All sound goes straight forward. Even standing at the side of the car they only sound like a normal car horn volume, but again... anyone in front of you is going to get out of the way FAST. It actually hurt my ears standing 5 feet in front of the car. I wanted train horns, but also wanted to stay married. These horns do the job great. I couldn't be happier. Solid product built incredibly well. Nice job Hella! I would totally buy these again. I was not paid for this review nor did I receive the product for free, nor am I related to, or friends with, anyone associated with this product. It's just that darn good! And they look super cool from the outside.

I cheaped out and bought some hella trumpet horns previously. They were a disappointment. Better sound, but not enough volume. Fast forward to these Hella Sharptones. These are made in Hella's India plant. Not quite as nice as the US or German variety, but they work just as well. Comes with the 2 horns and a 30A generic relay (Not a hella relay like the trumpet horns!). The relay isn't needed unless you plan on wiring a switch on your car. These little horns take around 4A each (8A for 2), so any car can have them wired directly without an additional relay. My little Nissan leaf only has a 15A relay with a 10A fuse and these things work fine. They are SUPER LOUD. At 4 ft, I measured around 105-110db. Pretty close to their 115db rating. They are directional though, so when you blast your horn, people in front will hear it a lot louder than elsewhere (but that's where you need it!). My only one peeve, is the horns "warble" a tiny bit. I'm not sure if it's the mounting, or just sound disortion. Not a huge deal. Overall, BUY THESE. They work extremely well! And unlike trumpet horns which you want to aim down (to prevent water pooling), these aim forward, where you need the sound to go.
