Super Loud HK Compact Air Horn with Compressor Snail Electric Car Horn - 12V 150db Nautilus Wiring Harness for Trucks, Vehicles, Motorcycles, and Trains Review

The horn is really loud. Exactly what I was looking for. The only thing I have is that the mount keeps pushing the screw out so it had to be modified to make it work.

The beep sound was quite loud once I figured out where and how to mount it. I checked the horn, the woman was in the house and she said it was pretty loud even from the house.

Very Loud Horn. Everyone around you will know if you use it! Installation required planning and additional materials. Wire, bolts and nuts etc. The Honda CRV has two small horns. I had to go downstairs to assemble this horn.

Bought 1 & failed; When in doubt I gave it, returned it and bought a second unit. just as bad as the first device. My advice is to pay a little more for something that doesn't take your free time to install and then return it. Jimmy

I like it very much. Moves big trucks back into their lane. Used 4 times so far to wake up people who like to check their phone at stop signs. It really helps that ignorant person who just turns in front of you, stops and sees you. Must be added for your motorcycle.

I installed this horn on my 2014 Custom Street Glide and I have to say it's one of the best upgrades I've made to a motorcycle. The horn is compact, easy to install and very loud. I mounted the horn behind the front fender and installed the relays and connectors where the old horn used to be. I highly recommend this horn.

. It produces a fairly high-pitched dual sound, more like Italian high-end cars. Also, I doubt it's 150 dB. I haven't tested this on a meter, but I have experience with audio and using dB meters. 150 dB would be insanely loud, it's just pretty loud. Aside from that, it serves my purpose of waking up the idiots trying to knock me out.

I love this horn. Although it was not easy to find enough space for it, under the hood of my Subie I am very happy with the end result. This is exactly the sound and noise level I was looking for. However, I feel a little sorry for the first PERSON who has to honk. I've used it to encourage native wildlife (deer, moose, etc.) to stay out of my way and they quickly agree. I would highly recommend this horn to anyone who wants to grab someone's attention very quickly.
