12V 150db Air Horn, Chrome Zinc Dual Trumpet Air Horn with Compressor for Any 12V Vehicles Trucks Lorrys Trains Boats Cars Vans (silver)

I only gave it three stars on easy to install because I had a stereo shop install it. This horn is loud. The button to operate this one is great. Everyone either love it or hates it. But it gives me the sound I was looking for. It’s loud outside of the truck but inside it’s really quiet. It’s useful and it will gain the attention of anyone As soon as you hung. There is no lag no delay the minute you push that button it blows. I did not have it connected to my regular truck horn

My horn works awesome, no, I don't think its as loud as a train, but it is very loud, louder than a truck horn. The directions were not elaborate, but still easy enough to follow. I used a separate switch in my UTV and wired it as it shows in the product pictures as on the listing. I needed a couple of extra connectors and a little bit of wire to use it in my application, the auto parts store had these items. When mounting the horn you need to be careful to tighten the screws evenly and don't over tighten ( the base seems to be cast ) I'm impressed with the horn and the price.

actually fitted directly onto the existing wiring loop- didnt need the extra wires - perfect sound

Very happy with this horn! It came with a nice wire-harness that allows you to feed into the original horn connections. No wire cutting, soldering, or crimping for my application at all. The most time consuming aspect of this install was finding a good spot for the horn & compressor. Plan to spend most of your time finding a good location to mount and you will likely need to drill a few holes in your engine compartment sheet metal. Horn is nice & loud, kinda sounds like a train horn just not as loud. Very impressive especially for the price!

Looks shiny and nice - but totally Just Junk. All plastic. "Mounting' bracket is a joke - almost a full 1" L - the only metal of the package, aside from screws.The compressor did NOT work at all. Before making a return, I did a 'reverse' hook up and got the compressor to spin backward - which seemed to loosen up, so tired it the correct installation and got it to work - AFTER slinging a bunch of oil out. Finally got the 'hook' up completed only to hear the pathetic squaaaaaack. Far from a truck horn, not even as loud as the factory horn for my 2016 Navigator - Depressing the horn for more than 10 seconds and you get this sick-cry of varied sound that fades to no sound at all - Just Junk

Worked well for a few months while on my Jeep, good sound. Stopped working recently and looked to see that the whole compressor unit fell apart. Tried reattaching but won't stay connected. Been on less than 6mon. Useless now.

Installed this on my motorcycle, as the factory meep meep wasnt loud enough. This solved the problem, and works great. The coating faded after a year use but didnt affect functionality

Started to fail, wouldn't fully blow. Just made a high pitch noise. Eventually failed completely, less than a year of service. When removing it, the cheap relay was completely corroded, I'm surprised it lasted that long. And it was placed high and dry in the engine compartment.
