SEINECA Car Horn 12V Loud Dual-Tone Electric Snail Horn Kit Universal Fit，12v Auto Horn Kit High and Low Tone for Truck Car Motorcycle Pickup RV SUV.

Installed on my Can Am Ryker 900 Rally. The horn that came with the Rally was high pitched and not very loud. This horn has a lower pitch with a bit more loudness. Nothing crazy, but to me, an upgrade worth it. Install took me less than 5 mins. 13mm bolt for bracket on Ryker. 10mm bolt to attach this horn to its bracket. And then reused the Ryker bolt to re-attach. Quality seems good. Sound good. Will update with any problems through I don’t for see any.

Installed on my 2015 Honda CTX700. Plug N Play, no need for instructions. Simply unbolt the factory horn (a single nut) and unplug the two wire leads. Plug in the new horn using the factory leads and mount with the same nut. Done. If it weren't for removing and reinstalling the plastic engine cover, this job took all of two minutes. And no more whiny "beep beep" from the factory horn. This sounds more throaty, like a car horn. It's louder with a deeper tone, both improvements over the original equipment and safer in traffic. Recommended.

Fit in stock horn position no problem. Not as loud as I wished but louder than stock. Good value for the money

This replaced the horn on my Honda 599. Much louder, and much more noticeable in traffic. Works great. It draws about the same power as the stock horn, so no relay needed.

Good loud horn

My overall rating is based on a few factors and the fact that the instructions that come with the horns are basically worthless and do not pertain to everyone's situation. I find it hard to believe that it pertained to anyone's situation. So, unless you already have a 2 horn set up, with 2 wires for each horn, it is not necessarily easy. However, I was not to be deterred and I am very mechanically inclined.To install: I had to do my own research to find out how to install a double horn system, to my 1995 chevy truck, with a single horn set up. After using my multi-meter and doing research on You Tube, I was able to determine that the horn I had was definitely bad, which is what I suspected anyway. But, I could not find anything that told me which of the 2 horn wires on my truck was positive and negative. But, with my tester, I was able to find out that the green wire was positive and the black wire with white strip was negative. (not that it really matters) So, I hooked the two horns together in series, using the included wires and added a male connector in between, to plug into my existing wires and connectors. I hooked both "Y" connectors to one male and the two "3" connectors to the other male connector. (Y and 3 are the only listing on the horns, instead of + and -) As just mentioned, it doesn't really matter which one you plug into the ground, or the positive wire. I took the included mounting brackets, attached them to the back of the horn and then crossed them in a manner where the two opposite ends overlapped each other to mount with my single bolt ground setup. Basically making the two horns touch one another and pointing at as much of a downward angle as possible. Once grounded to the chassis, with my existing bolt, to where the original horn was installed, it worked fine. I also put electrical tape over all exposed connections, to try to keep as much water off, as possible.Good points, is that they are a great value and the horns are rather loud, as I hoped. So, the video did not lie about the sound level. They are just a little wimpy sounding for a Chevy truck. It sounds more like a Chevy car horn. But, at least it doesn't sound like the wimpy horns on Japanese vehicles. (don't get me wrong, I love my Japanese vehicles, just not the horns.......LOL)

Not sure why but the factory horn on my Harley gave up the ghost. Taking it all apart, it seems to have just self-disassembled in some fashion. This was a simple 1-for-1 swap, essentially identical in size, took hardly 10 minutes with basic wrenches to re-mount where the old one was, and sounds more powerful than the original. Seems good quality and value; hoping for another 12 years from this one and will update if anything should ever change my mind.

It’s a horn.
