FARBIN Air Horn for Car Loud 12v Car Horn Kit with Relay Harness and Button

150 db....I do not know, however, when I got them all hooked up (got the 2 pack) and tested, the wife was in the house of our attached garage, and she about jumped out of her skin. Installed on a 2004 Silverado. I have no doubt that I will get the attention of the xxxx's that cut me off while I am pulling my trailer now!!! Way louder than stock. I did build a nice bracket for them to mount to that sits behind the bumper.

Great horn, loud, EZ to install and great price. When I blast the horn, every vehicle freezes. Everyone clears the way and no one opens their car door into traffic.

so far I am happy with it, its not too loud but it sounds like a truck horn instead of an icecream cart. The black wire was a little short so I dropped a star but besides that fits like a glove in stock location and super easy to hook up

After i showed it to the mechanic, he told me its above limit for a small car, but still legal in the country, its designed for pick up trucks and heavy vehicles, he pointed the horn downward so its less loud than usual, however it sounds Amazing, definitely its worth every penny

This product came with no instructions other than a blurry diagram on the box. There were also items in the box that I had no clue what they were for.

Read on for some tips and ideas for installation... Not much to complain about here! I have three of these in service in my vehicles and am very pleased. Much louder than any stock horn. Consider this a small investment in safety. You can find "Y" adapters for the power hookup on Amazon for your specific vehicle brand, so installation is pretty much plug and play. On my 2019 RAV4 I simply moved one of the two factory horns and combined them on one mounting bracket, then installed this on the empty bracket and wired them up. The difference is major. For the electrically savvy, you may want to consider my installation method: I power the relay for the thing from the accessory buss (the accessory wire that is only on when the car is on or you have the key in "acc" mode), that way this really loud horn only works when the car is ON. Why, you ask, is this important? Because when the car security alarm decides to go off at two in the A.M., you might be happier if the trumpet of God isn't blowing outside your bedroom window. I also put a switch on that wire just because I could, but I almost never turn it off, unless I'm outside someone's house and just want to make a quick "toot" without scaring the neighborhood. Combine this with a set of Wolo "Long Horns" (I've done it) and you get some serious scary noise! UPDATE: I recently added another set of these horns to a vehicle, this time I added one of these and a Farbin "Raging bull sound horn", ASIN number B08L9G7BNL, Farbin part number FB-NJ. The sound is quite impressive. Let me state at the outset, that you will not necessarily be impressed with the bull horn on its own, but COUPLED with this air horn and the factory horns on the GM vehicle I worked on, the tri-tone sound (it tends to get humans attention lol) is VERY train-like. I used 14 Guage wire to supply power and an equally heavy wire to ground. If you're willing to do the extra work for the customization, the effect is very rewarding. I won't go into the details, but let me assure you I have NO PROBLEM getting people's UNDIVIDED ATTENTION when I hit the horn button now.

The specifications on this horn is not accurate It claims to be 150 decibels I bought three of them On the outside of the package it clearly shows each horn is 125 decibels And as for it sounding like a train horn no it does not sound like a train horn.

Amazing product and excellent quality.

Excellent horn, very loud. Love this horn.

It’s a good quality horn, easy to install either instead of your existing horn (clear instructions provided) or as addition. The sound is pretty loud although different to a standard car horn sound (more like a boat or truck) a bit on a higher note so definitely raise attention of anyone in vicinity. My horn was not working at all so i installed it as a completely new system. Wires are good quality, press button too. The only thing is the wires that go to battery are to short and needed extensions if you are to place the horn on usual spot which is at the front of engine bay and near front bumper. Other than that it a great quality car horn.

For such a relatively small horn, it packs a good sized sound. Not quite the same deep note as a big rig horn or a train horn, but impressive nonetheless.

Not loud as mentioned

Works very well
