HELLA 3BB 922 000-731 Air Horn

Arrived from India in a very battered box but well wrapped so I was dubious they were not new but they do appear to be. Easy install, though no instructions are included if you’re not electrical. Sound is loud enough to do what they need without being offensive.

Packaging could have been better, the box was a little damaged but the product itself was in good condition. Appear to be the genuine Hella product as advertised. You get a relay included in the box however I didn't use it. You don't get any wires in the box so you will need to get your own, and make a connection between the two horns (hi & lo) and a connection from the hi to the vehicles original horn wiring. I had to remove the bumper from car to access the original horn and wiring, I then attached them to the crash bar behind the grill. The sound is loud, and the tone is a bit lower than the red Hella horns but still a lot higher than a standard snail type dual tone horn. I would recommend this horn to anyone looking to make their original horn louder or if you only have a single tone horn. There is an app you can download which allows you to listen to the different horns. Just search Hella Horns in the respective app store\play store

Great product, not an air horn? But good quality and work. Definitely louder than the stock horn. Would recommend. However it's not an air horn.

Not as Loud as the Red ones

Great horns and sound good as well,easy to wire up just need some spade connectors

This horn can produce a harsh enough note to fail the standard MOT test. Mine failed it's MOT on the horn note. Do not use as your main horn. If you want a louder horn, go for it but make sure you have a horn with a more subdued note as your primary horn for MOT purposes.

Good quality and does what it should. Quick delivery.

Was a bit suspicious of price and ship time but actually arrived in good time and are fully original/legit

知人のゴルフ5に取り付けました。音を聞いて気に入って鳴らしましたが、下向きで取り付けなので、音が篭ってイマイチです。

I really need to find louder horns, but that is more because of the car these are on then it is the horns. I installed them on a 1967 Mustang I purchased that didn't have any horns. As long as the car is off these horns are LOUD!!! Unfortunately for me, the car is louder. lol

Au top, son puissant et propre, façile à installer une fois les branchements adaptés au double klaxon. Résistant aux intempéries malgrès le montage directement dérrière la calandre et donc exposé à la pluie/boue/etc...

Looks good and performs as expected.

Build quality is superb. Sounds great. Volume is moderate and on the soft side. Go for it if you are looking for a high quality normal level quality sound
