Review on 🔊 Hella 12V 002768551 Disc Type Horn with 118 db Sound Level by Tom Roberts

I installed this horn along with the same part of the 12 volt series ending with number s 8551. A pair, one 335 and one 400MHz, has the same frequency and sound as all Mercedes cars before - 2003. They installed on my 2007 Mercedes ML350 in less than 15 minutes. Finally, one of the factory horns was completely out of order. It was an inconspicuous overall sound typical of an American car, which did not inspire any respect. These beeps are loud and noticeable. I'm very pleased, although I wish they were bundled together and simply marked with 12V Hella 335 and 400MHz disc horns.
