People can now hear me in my miata!
Sounds good! My old miata only had one horn which was broken and useless. I had to crimp a new connector with a 2nd wire coming out to hookup the other horn. Simple install and now people can actually hear me.

Sounds Louder than OEM!
I used it on my 2013 Scion TC and it is definitely worth it. A cheap $20 modification that will be useful when driving everyday is a deal. Sometimes with my stock horn I felt like people couldn’t hear me, with this its loud enough so they can hear me, but not loud to the point it will be obnoxious. I feel like it is a good mod, cheap and get a great outcome out of it, best of all it is plug and play and works better than the stock ones. I will be doing it on my other cars I ever get in the future.

Loud upgrade from stock, it will sound like a 90s Japanese Car
I like to write reviews on products 6 months or more to really give an accurate review, and to really see if these products hold up after the test of TIME, and use ofcourse. Bought in 2022-2023 for my 2007 Nisssn Sentra . It wasn’t a direct fit, and my factory horn was a single note and these are double note. Which is ok, cause that’s what I wanted. Not only does my Japanese car sound like a Japanese car now (Horn beep) it is LOUD!. Louder than my single note original. It was a cool upgrade, still works well years later and sounds like a 1997 Toyota Camry. Make sure your connection is good and bolting location is clean and rust free, that’s important

decent 2012 RAV4 replacement
A pair of these are lower cost than two OEM Toyota horns. These mount and connect to the harness same as OEM. Nothing is going to make any 4.3gen RAV4 horn install easier since you have to remove the entire front bumper. Make sure you have some spare clips and bolts ready for reassembly; those parts do not always age well. Loud enough and hopefully will last as long as the OEM horns did. Seems that the current draw from these will play nice with the OEM harness...no need for another control relay. Minor gripe of growing tired of everything made in china though.

Beep beep
Nice horns. They go beep beep. Easy to install.

Really, Toyota?
These are inexpensive replacement horns for our RAV4, but Toyota should be ashamed of the junky, weak, ineffective, and tinny Denso horns they install at the factory. I'm aware that the pennies add up when building a car, but these are a huge improvement for less than $20 retail. They compare favorably with the Hella Supertone horns I installed on my 2017 Corolla iM, but don't require a relay and are a direct replacement, including the power receptacle. Easy to install, requiring only a 10 and 12mm (wrench) socket, along with a small flat blade to pop the plastic retainers under the hood. I completed the job in about 30 minutes from start to finish, so this is an easy one. Highly recommended and a critical safety improvement for any car with factory Denso horns.

Simple upgrade for base model Subaru
One way Subaru makes their base model in the line-up feel cheap is by installing just a single horn. The mounting bracket would accept a second horn, but there is no wiring in place and also on 2020+ models, bumper fascia needs to be removed to access the horn location. These 77 mm Hella horns can be mounted on a piece of angle stock attached to the threaded rod holding the battery, as shown in another review, which also shows the wiring. Wiring is easy because the battery and the fuse box (used for tapping the relay trigger off the existing horn fuse) are right there. The horns are compact enough to fit within the space in front of the battery, to the left and to the right of the windshield washer filler neck. At the same time, they are still larger than the factory horn. Now my base Subaru Legacy has horns that sound properly, actually three of them including the factory one. Highly recommended.

Seems to be genuine, works well too, just wish it was a tad louder (comparing to Hella Supertones).

Thicker than original Toyota Denso horns but shouldn't be a problem for any vehicle since horns are not placed in places where there's no wiggle-room. Connectors fit perfectly, though appear to be on the opposite sides of the original horns. Toyota's original wiring becomes somewhat taut but still doesn't direly affect anything. Horns sound phenomenal. I didn't look close enough and just installed them. Usually the low frequency horn is attached at a lower level at the level of the bumper while the high frequency unit is placed next to the front grill. Not sure if reversing this arrangement will affect sound dissipation. I doubt it!!! Still the combined sound is amazing and hopefully it serves its purpose on the road. The horns are listed as corrosion and water-spray proof. If both these claims hold true I think this is the best purchase I ever made since original Denso horns were $ 130.00 each. So overall I saved $ 260.00 plus tax and installation fees. That's quite amazing considering these horns sound so good and claim to possess additional long-lasting qualities. Time will tell. Regardless, I am content.
