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

Update November 2019 It's been almost three years since I installed them and they look and work the same as they did the first week. I avoided at least two accidents with this setup. If you get the installation right (with a relay and a direct connection to the battery post) you have something that makes a noise that needs attention. I've had too many calls in the parking lot and close conversations with people so distracted by their kids, phones, and general inattention. The same qualities are given to people at crosswalks, immobile pedestrians, and impudent cyclists who insist that I share the road, but they don't obey the highway code. I swear people don't love or appreciate their lives, at least that's what they tell me when they walk in front of me without looking up. My previous horn had a friendly, almost street-ready "beep-beep," and is hardly a result of my sometimes necessary and prudent use of the horn. Something needs to change and that is the addition of these Hella Supertones. When testing the horn, it was loud. I figured it wouldn't be a deafening, isolated source of noise. Instead, there's a full frontal attack from a source that's the size of a car in cross-section. It seems more like "dirty your pants" than "make your ears bleed"... which is fine with me.
