🚛 Wolo (847) Siberian Express Air Horn - Electric Air Horn for Vehicles - 12V Solenoid Operated, Black Review

The horn works fine for a while I bought the first one but after a few months the big horn broke I bought the second one and after a few months the big horn broke

Easy to install. Especially if you're replacing your crappy old horn. It has a really nice train sound and is loud enough to get people to stop and watch. They're a bit bigger than I thought, but putting them in the same spot as my standard horn on my 2012 Prostar has no problem.

I bought these to replace a quad tube I've had for years. I've had them for about 3 months now, no complaints. I chose plastic for two reasons: weight and rust resistance. My set of quads were chrome plated and heavy as hell which ended up killing them lol. They're a lot lighter and I think they're even a bit louder. I would buy them again.

The horn sounds good but I think it started buzzing a little, removed the electromagnet and ran a 1/2 inch air hose from the 5 gallon tank. It's really loud but makes an odd high pitched noise, again it wasn't made for 1/2 air hose at 150 PSI lol but will hold up and love them. Product A++ for cheap plastic!

I love these horns! It took me a little time to get them hooked up and running in my trailer as the manual valve I ordered was not compatible with the RV. I didn't have a place to install it that was easy to get to. I ended up having to order a separate solenoid valve and fit a switch so I could choose between an air horn or a crazy little OEM electric horn. Unfortunately it cost me extra money but I am very happy with the performance of the horn.

I prefer these Wolo horns to Hornblaster horns. They may be plastic, but I think that prevents them from making a high-pitched, tinny sound. When I think of railroad horns I think of a low horn, not a brass horn. My only complaint is that you can't remove and install the horns from the common header so you can separate the horns for easier installation elsewhere on your car.

When I bought this I thought the stick body was aluminum but it's plastic. I've seen about 50 photos of different owners complaining about the trunnions breaking off. It's much better to have an aluminum diaphragm lifting mechanism so the diaphragms can be replaced rather than the entire unit. Also, they are very noisy, so they got rid of that, maybe they will start making them from a more durable material. Otherwise I like it so far. Just don't watch them last long. Many Thanks

I paired this horn with a Wolo 830 Sherman Tank & Compressor All-in-One and they match perfectly. These things are LOUD. When you plug your ears, you can FEEL the pressure. Look carefully at the measurements. These things are massive. The step is close to the train, but not exactly. You won't care Believe me. Only about $105 which is 30% cheaper than manufacturer's website or other retailers. They saved my frontend from deer the first morning after installation. A tip: Make air and electrical…
