Loud 12V Automotive Horns That Were Easy to Install
I picked up this pair of 12-volt automotive horns and they’ve worked out really well. They come in a simple black finish and have a basic two-terminal setup—one for positive and one for ground—so wiring them up was pretty straightforward. The box included everything needed to get them installed, including the mounting brackets and pigtail wiring, which made the whole job easier. For the ground, I just wired it to the mounting bracket since the bracket was already grounded through the vehicle, and that worked perfectly. Once installed, these horns were definitely louder than I expected. They have more of a higher-pitched tone rather than a deep truck-style sound, but they’re sharp, clear, and very noticeable. If your factory horn is weak or barely gets anyone’s attention, these are a solid upgrade for the price.

Great
Great horn replacement. Sounds almost stock on my old dodge Dakota, its not very loud but perfect and gets the job done. Cheap and easy to replace. Looks to last the life of the truck hopefully

Great improvement over OEM horn
I got this to replace my factory OEM horn. The original was very weak sounding and I wanted something a bit more "attention-grabbing". This was easy to install and sounds a lot better than what I had before.

Works like it ought to.
Works well. Easy to install and connect. Probably as loud as the original horn, but not louder.

Loud, proud and two-tone sound.
My Jeep had one horn, and it worked intermittently. I prefer the sound and volume from two horns over a single one. Space was a little tight, but I managed to mount them both with a little bracket modification. Very pleased with the sound and looks. These definitely produce a sizeable amount of volume and will get your attention.

Very great horns
I absolutely love this horn, great for your car, pickup, SUV, boat etc... It's amazingly loud and very easy to install. It fits perfect at the front of my car and very easy to mount. It's safe for every day use and will not damage the ear. I recommend this product and the seller's service is exceptional 👌
