HELLA 003001671 Triple-Tone Horn Kit with 12V Air Compressor and Mounting Bracket

Completed one year & 2month, it's still working like new one. Excellent product,i have fit to my force cruiser(toofan),it's like train horn,big truck give a side quickly.its much better than symphony and vibrosonic and megasonic horn.i have use this horn atleast 50 times in a day.

It's an amazing horn if you want other vehicles to listen to you and give you side. Bikes and other small vehicles easily get on the side with one roar. I've been using it since 4-5 days and I can say that horn is a bit loud but it's really useful to cut through the traffic. Don't you it when someone is really close or for walking people. I've seen that out of 10 times, people roll their necks to see which vehicle is coming at least 6-7 times. So it can grab people's attention easily. Totally worth the money.

Please don't take this product. I received the product with box and seal tampered. But the shipping box was perfect. Also the product I think it was returned by one of the customer and I could find a sticker cutting blade inside the product which is not the part of the product. Also the product was not working at all.

Compressor cap small crack Small scratch Sound was superb

Love the Hella trumpet air horn, 4 stars because it was badly shipped and dinged the trumpet a bit otherwise it's a great piece of kit, it's illegal to fit these on motor vehicles in India but the laws are not always wise to the needs of highway safety. This thing brings the attention of even the biggest and loudest rigs on the road to your presence and definitely improves rider safety on the highways. Also it's a brilliant design where it can be quickly unscrewed and concealed to avoid the cops from impounding your vehicle. A bit of a suggestion, keep your stock horn in place use a dual horn wiring harness with a handlebar rocker toggle switch to switch between the stock horn and this beautiful monster. Ride safe and don't be an obnoxious rider by making noise near silent zones. Cheers.

Sounds like marine horn Loud but not irritating. For city use not advisable.

Good one...works well and useful in high ways and rural where there is no road sense

goood horn but horn relay not working

Sehr gute und legale alternative zur originalen hupe. Man braucht hat den platz und die nötigen Elektrik Kenntnisse um diese Fanfaren zu installieren. Das ist definitiv kein Plug and Play Artikel. Ich habe bei meinem e46 alles hinter den Stoßstangenträger verbaut. Da sitzt es alles sicher und bekommt relativ wenig Wasser ab. Ich habe das Set jetzt fast zwei Jahre in Benutzung und es funktioniert noch alles wie am ersten Tag. Durch die Hauptuntersuchung bin ich damit auch ohne Probleme gekommen. Ich würde das set jederzeit wieder kaufen.

Super und einfach zu montieren

My compressor stopped working after only 9 months of use. I am an occasional horn user and for such a critical part on a vehicle to fail so quickly from a reputable automotive products manufacturer is very disappointing to say the least, on top of being a vehicle operation safety issue. But when the horns worked, they sounded loud and very lovely!

I've owned a Hella DOUBLE-horn before (without the stock horn engaged) and found that some people still don't recognize the tone, despite being loud enough. I wanted to go bigger this time because some people on the road simply don't pay attention to my factory horn until it's too late. I'm running the triple horn with the stock horn so these 4 frequencies do a great job at providing a full-spectrum and piercing sound that gets the proper attention. Depending how much room you have, 3 horns plus a compressor can be tricky, but they can all be mounted separately (may need some extra tubing).
