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 !

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 am researching for weeks about horn replacement. In reddit, Hella is well recommended. Same with other car forums that I get into. So I give it a try and compared to the stock version of my car, Hella is way better. It’s truly loud. Its comparable to the ones being used by SUV.

Great units, only slightly larger than my OEMs so no issues with fitting them in the current mounts. HELLA also provide a relay for those who need one of this size (already had one OEM so it's a spare for the bits box). I needed to run an extra earth cable which gave me chance to clean up some wiring (oem were denso which only have a positive). Overall lovely product, nice secure packaging and performs well. Have noticed that even though people can't see me, they pay attention to the horn frequencies alot more.
