Review on 🎺 Hella 012010801 Blue Trumpet Horn Kit: Powerful 12V, 400/500 Hz Universal Fit by Joseph Lang

Used these to replace the horns on my 2008 Toyota Prius. For those who own at least a 2004-2009 (possibly later generation) Prius 2nd generation, these horns will replace your standard silent horns. BUT. It's very important that you understand that this is a two-pronged horn, so it requires a little extra wiring. Believe me, a person with no experience, this is not so bad. What you need to do is plug in the original adapter (after removing it from the original horns) and then plug it into the top "16" connector on the horn. The next step is to create a ground wire (I used a 16 gauge + 1/4" female adapter + 3/8" ferrule adapter) and attach it to the bottom "10" terminal of the horn to allow it to ground looks like the photo below. These horns sound much better, deeper and like a real car. Run them through El Grande or Freeway Blasters.
