Review on 🚗 Hella Supertone High Tone Horn H31631021: 12V Single Horn with Red Protective Grill by Jack Herrera

I have installed Hella Supertone horns on several cars over the years. The set I bought from Revain for a "great price" broke down after only a few months of installation. I've just had the opportunity to remove the bumper from the car again to diagnose the horns. I hooked them up to one of my other machines that also has Hella horns that work fine. They only uttered a short cry and nothing else. From this I can only conclude that this is the case if the product is not genuine. I see Hella offering a 12 month warranty with a broad disclaimer that they must be installed by a 'professional'. I'm a car collector who would never let a "pro" touch my car. But it looks like Hella is dismissing me as unqualified to install .horns. So even if they are genuine based on this obviously unkind point to avoid any opportunity to endorse their product I will not waste my time with Hella for a replacement.
