Love them, easy to install

  • It wasn't as represented at all.
Color: Red
Very disappointed...not train horn or easy installation. Did not include directions as stated. After all the stuff that had to be done, the actual truck horn was at least as loud as "300 db train horn" that did not sound anything like a train. Would not recommend this item. Would not have given the star if it would let me submit review without it. ... show more

  • Not Bad, But Let’s Be Real—These Are Not 300DB
Color: Red
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 ... show more

  • *ALL CAR HORN NO TRAIN*
Color: Red
Say “train horn” it’s a car horn, I bought it for my nephews 4 wheeler, sounds like he’s in rush hour traffic in the middle of the woods instead of a train.
