🚂 Ultimate 300DB Train Horn Kit: Loudest Electric Snail Double Horn for Trucks, Cars, Motorcycle, Bikes & Boats - Waterproof, Raging Sound, 12V - A Pair Included Review

Two 150 dB horns do not result in 300 dB. It takes 14 to 15 pipes to sound twice as loud as one. Similarly, 7 or 8 pairs would be needed to achieve 300dB.

I'll turn them on tomorrow. So far very satisfied. I did notice a small flaw with the plastic volume knob, but I don't think it matters. However great value.

It's easy to use and not expensive at all. However, this is not a train at all. This is a car horn, not a loud car horn. It's a lot better than my stock motorcycle horn though, so it's useful.

That's NOT 300 decibels! My Silverado's stock horns are louder than these and don't sound like train horns in any way. I wish I could send them back but I've already installed them and taken them off the truck. DO NOT BUY !

This was used on a van, the original horn was removed and replaced with these two horns and the sound is quieter than the factory horn. I am very dissatisfied with this product and would advise against purchasing it as it is not what is advertised in the description.

Both horns must be 300 dB. Still a solid product. If you are mounting them on a motorcycle, you may have difficulty accessing the nut to tighten it due to its wide neck. Even at 150 dB, this horn is louder than a normal motorcycle horn. Rated 3 because I paid for what I expected.
