I’m looking for a truck Airhorn / Trainhorn to install it in a car. Actually, the thing would be clear, the Nathan K5 is the measure of all things. However, the dividers also weigh 50kg, are very large, need a giant tank, compressor and cost a lot.http://lufthorn-airhorn.ch/nathan-airchime-k5hl-powder-coated.html Which airhorn can you recommend? Is there a solution that can do without a compressed air tank and is still loud (direct compressor on horn)? Is there something ko mpakter air horns that don’t sound equally ridiculous/cheap.Do you have any further tips?The solution will not be used on the streets and will only be used for show purposes on private areas outside of Central Europe.
