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

Great horns but the packaging needs to actually protect them.

After only a matter of months with these being fitted the paint is flaking off and going rusty Waste of money - not simple to contact seller either!!

Sound quality is terrible and not consistent. Not sure how people are rating these horns positively! Limp and diluted. Sound like you got two different cheap horns from two different manufacturers. Maybe using either one by themselves might be ok, but together, they are completely out of harmonic balance.

Just Great well worth the money - just check you have OE not counterfeit goods - hologram

No louder than original horns

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

There are no dimensions on the listing for this horn. The listing says it'll work for a motorcycle, but at 5" in diameter it way to big for any motorcycles that I know of. The standard size for motorcycles is 3". I'm sure it could be a great horn for anything that can accommodate a 5" diameter horn.

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 !

Got this as a gift for my brother for his can am. Works perfectly and is very loud so others can hear him. Great value for the price. Would buy again.

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.
