Yeah - I agree - the website is a bit funky. It took a minute or so for it to load for me too. Once there, make sure the "Passenger Car" is highlighted in the top ribbon, then click left on the bottom ribbon until the Supertone horns are highlighted. Then at the bottom, click on the "HIGH + LOW" button. You should hear the horn sound.hanks for the link.
That’s a weird website. The Hella webpage took forever to load up; then I wasn’t able to navigate around. I guess “Noise” is to mean “Sound”? Either way I couldn’t hear a horn.
Hope their horns are built better than their webpage...
Ifyou should decide to get them, you don't have to deal with their funky website. Lots of places carry the horns (Amazon (Amazon.com: HELLA 003399801 Supertone 12V High Tone / Low Tone Twin Horn Kit with Red Protective Grill, 2 Horns (3AG 003 399-801): Automotive ), JEGS (Hella 003399801: Supertone Horn Kit Voltage: 12V | JEGS ), etc.
