06 Highlander horn
Replaced the wimpy horn on my Highlander with this. Easy plug and play install, and it sounds like a normal car. The electrical connection on the Toyota option fit perfectly. I had to polish the paint off of the screw hole in the mounting bracket though, as the factory horn's circuit grounds through the metal-on-metal contact between it and the car. Keep that in mind

Good upgrade over those old OEM ones.
Decided it was time for some new honkers for my 1998 4runner since my oem ones were dinkie and sounding really funny. One of them went bad and gives off a strange sound. Put these on an they are an awesome upgrade. Horns are a much louder & have a deeper tone and demand attention when used! Thankfully toyota is toyota and makes it easy and has been using the same single pin horn connector forever so they plug right into my factory horn wires. For you 3rd gen 4runner and probably 1st gen taco people out there the horns in the toyota kit will fit but you will have to do some slight modifications to one of the horn brackets. but it's very easy. First thing you'll have to do is adjust the connector on the horn. They come out the box at the wrong angle for our trucks and the horn wire won't reach it to put in. They rotate though so just push down hard on the connector to make it spin around. It spins but it's very stiff so you have to push hard, don't be afraid to. First photo is after I rotated them. Secondly, at least for my 4runner the passenger side horn didn't fit because of the ac line right next to it. All I had to do was drill a hole higher up on the bracket to clear it. roughly 31mm from center of the old hole to the center of the new hole. In the pictures it looks like it's touching the ac line but I promise you it's not. Its about a 12mm gap in between it and the horn so it's plenty of space. You will also have to use a regular box end wrench on the passenger bolt now since the horn is moved up and blocks socket access from the front. Overall really liking these new horns so far, they are good value and definitely work well and they fit great even though they are larger than the ones I had before. They aren't touching on any part of the grill or other pieces around it either. Easy good upgrade!

Good sounding horns, some tweaks were needed….
Installed good and just fine and fit in my 2025 Toyota RAV4 hybrid. Sound is what I expected. The reason I gave 4 starts is solely because both horns were positioned for one side installation, meaning, the long metal part that screws in and grounds the horn, was positioned on both (2) horns that required the plug section to face out instead of down where the plugs are. I moved the metal part around to the opposite side so each horn had the plugs facing down for easy reach of the plug. Other than that, it is all good. Also, the screw hole did not need to be sanded down to show silver metal for grounding. It was already good to go (others have stated that they needed to do this).

Easy install horn quality excellent.
These horns are awesome. They sound perfect and the install was extremely easy and quick. The only thing you need with these horns is a seperate 12v wiring harness that plugs into the existing ground, and 2 leads to plug into each horn. It was $20. Wires get messy after install but nothing a zip tie or black electrical tape can’t take care of.

Now That is a loud horn!!! Much better.
Tried some no name horns and they were all terrible. This set made a huge difference. Much louder and did not need a relay. Used the factory horn harness with a splitter. Works great.

Perfect for 2013 Toyota FJ Cruiser
Bought these to install in my 2013 FJ Cruiser. My FJ only came equipped with the low tone horn. It sounded weak and embarrassing. I was going to buy the high tone Toyota OEM horn to add it to my current set up but it cost more than a pair of these Hella Horns. After reading reviews I opted for these which come with the Toyota connector so the install would be plug and play. Bought a 1 to 2 way adapter with the same Toyota connectors just to plug and play since my FJ only came with 1 connector since it was equipped with only 1 horn. Hella Horns have an excellent reputation for their high quality horns and made an immediate upgrade to the sound output of my FJs horn. Not embarrassing to push the horn anymore.

Money well spent the second time
Bought this back in 2022 to replace the weak factory ones that came in my vehicle, perfect for the last almost 4 years LOUD, STRONG and definitely gets quick attention when I’ve had to use it. Unfortunately just recently one gave out, so guess who’s gonna be a repeat customer? Yep just purchased another pair, money well spent
