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

Installed on 2019 Forester - Louder than stock, easy to wire up. Cost was great, relay was included. I didn't want to have them be a focal point behind the grille so I put a few coats of flat black paint over they yellow. No issues and all working as expected.

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.

Sounds great, good price. Easy to istall

Hella Corp. has been in business for a long time manufacturing quality products so I just hope this is another example, these pair of yellow horns were made in India??? These horns are noticeably heavier and a little bigger than the stock Ford OEM horns and sound almost just as loud. The write-ups had me believe they would be LOUDER than the oem horns, not so! I tried both the direct battery wiring connection with the enclosed relay and the straight factory connection without the relay, and noticed no difference in sound loudness. With some minor adjustments so that both of these horns fitted well within the confined space of my vehicle, I connected these horns using new 10gauge wire and secured them to the vehicle. Walla-they worked-they look sturdy, they are heavier, they are a bit bigger, and sound about the same as the stock horns, but now have that modern wimpy sound of all of today's vehicles, only louder. So I hope they last just as long. Wish the yellow horn covers would have come painted black from the factory but they can be painted any color you want, just by taping around the yellow covers and spraying or removing the covers. These are universal fit horns so expect some minor modifications during installation.

So much better than the stock horn on my Subaru Legacy. Still a little shrill but doesn't sound like I'm driving a smart car. Only thing I had buy extra was the harness adapter. Oddly the one that fit was for a Toyota. Super easy to mount with one bolt. Slightly larger than stock but we're the go they could have been about 8 times the size and not been an issue.

NICE AND LOUD!Very easy to install. No relay needed. There is only 2 wires for the horn. Positve and negative. Just connect the old horn signal wire to one end of a new wire using a spade crimp connector and connect it to both horns on the same conectors of each horn using 2 more spade crimp connectors. Then make a second wire connection to both horns on the remaining spade tabs on the horns. the negative spades using 2 spade crim connectors and at the other end use a crimp terminal ring connector and find a bolt to ground it out on. *if your horn is a negative and then a positive you can just reverse the connections. But o found that there is no positive or negative marked on the horns. So you can hook them either way and they should work fine. They worked so well i got a 2nd set for my wifes Prius.

Bought these based on others’ reviews, especially on the TacomaWorld forum, claiming they are louder than the factory Toyota Tacoma horns.I can only assume that either the reviewers were embarrassed about wasting their money and wanted others to waste some, too, or they simply jumped on the “aren’t they great” bandwagon.These Hella horns are okay. Very average electric car or motorcycle horns, higher pitched than the normal Tacoma units and for sure not as loud. I have my hearing checked annually for work and am better than average, so I’m quite sure it’s not my hearing.Are they good horns? Sure.Are they super loud, attention-getting horns? Nope.Are they louder than 2019 Tacoma horns? Nope.It’s too late to return them so I’ll use on my old Land Cruiser - it needs a new one anyway. But if you want an upgrade over stock…not at all.
