Louder than OEM horns
These horns are great, and plenty loud. I almost didn’t buy them because of several negative reviews. So no, they’re not as loud as a train horn. To achieve that you’d need to buy an air horn complete with compressor and air tank. They are made of ABS plastic, just like the OEM horns. They do not come with a wiring harness, but making your own, if you have a wire crimping tool, could not be much easier.

did not sound as advertised
does not sound like a train horn. just a regular sounding horn. and Amazon wants to charge me $7.99 for a return box. .5 star for the product and .5 star for Amazon. Nice job taking care of your now former customer!

Great so far
First day review. Installed fairly quickly. Definitely not 300 db but loud enough. Replacing the stock horns on my 2002 f150. Had to cut and splice some spade connections. Also used some shrink tubing for added protection. Bolted to the stock bracket and spliced into the original harness for OEM-like fit.

Good product
Not as loud as their title says. It's loud but not train horn loud. Used on our SXS and it works good. We just wanted something louder than the stock one and it does the trick. Feels durable and it was easy to install.

You get what you pay for
So I’m only giving it the 3 stars because it sounds better than what I had going on to begin with. It’s not as loud as they claim and definitely not a train horn. But it does serve its purpose and didn’t break the bank.

Sound like regular horns not any more loud than regular ones.
They work just fine for a 12 buck high and low horn set up. Nowhere near sounding like super loud train horns though. Sound is regular tone and volume. So that's why it gets 2 stars because the title is not accurate at all.

Not Bad, But Let’s Be Real—These Are Not 300DB
I bought these horns because the listing made a pretty bold claim—**300 decibels**. That’s not just loud, it’s *physically impossible* loud. Just for reference, a real train horn maxes out around 150db, and 300db would literally rupture your eardrums and probably shatter your windows. So no, these are not 300db. Not even close. That said, I didn’t expect *literal* train-level sound for the price, but I was hoping for something a little more intense than a stock car horn. Unfortunately, while these are definitely *a bit louder* than factory horns, it’s not by much. I’d say they sound somewhere in the ballpark of a decent scooter or maybe an older motorcycle—not exactly earth-shattering. Installation was straightforward enough. The wiring isn't too complicated if you have a basic idea of 12V setups, but there were no real instructions included, which could throw off beginners. I ended up watching a couple of YouTube videos to make sure I had everything hooked up right. Mounting was okay—although the bracket feels a bit flimsy and I had to reinforce it with some washers and zip ties. As for the actual tone of the horn: it's more of a sharp *meh-MEEHHH* sound than a commanding *BWWWAAAAA*. It kind of resembles a clown car mixed with a cheap alarm. It’s not terrible, but it doesn’t exactly strike fear into the hearts of inattentive drivers either. If you're expecting a legit "train horn" style, this isn't it. Pros: ✔️ Cheap ✔️ Easy to install (with a little DIY knowledge) ✔️ Slightly louder than stock horns ✔️ They *do* work, and they’re waterproof so far Cons: ❌ Not even close to 300db ❌ No installation instructions ❌ Brackets and materials feel a bit low-end ❌ The sound isn’t very deep or powerful Overall, it’s an okay upgrade if your current horn is completely dead or super weak. But if you're buying this thinking you're getting a mini freight train in your engine bay, you’re going to be disappointed. These are fine for the price, but definitely not the beast mode they’re advertised as

ليس بتلك القوة
ليس قوي كما هو مذكور وصوته غير مناسب لبعض السيارات الكبيرة. لقد تم وضعة في سيارتي سلفرادو 2500HD. وتم نزعة وفكه لانه غير مناسب صوتة الضعيف مع هذه الشاحنة القوية. جودة التصنيع والمواد خفيفة
