Description Reviews Hella Supertones are an excellent choice for drivers looking for powerful, attention grabbing horns. The very loud and powerful dual Supertone horns add a level of safety to your driving with 118db(A) of sound. Hella Supertones create a far reaching warning signal with a sharply focused sound emission excellent for freeway driving. The Hella Supertones are encased by a rugged ABS housing with red protective grille that can be removed and painted to match your car if you mount them in a place that you can see them. Hella's Supertone horn kit includes: 2 disc-type horns (one high-note & one low-note), a relay, mounting hardware/bracket and installation instructions. Loud 118db of Sound Black Body Red Grills 8.58" Height 7.32" Width 3.50" Diameter 12 Volt Note: This kit will fit any MINI, but you will need to trim the core support a bit to make the larger horn fit correctly on Gen 1 cars. It's a simple cut that you never see and doesn't affect the car at all. On Gen 2 cars they are hidden totally in the bumper and you just need one nut bolt combo to mount one horn. You have two options to plug the horns in. You can clip the wires and plug them directly into the horns, or you can make a small harness that plugs into the harness to leave all factory harnesses intact (see above photo),no relay needed ever. Note:The R60/61 has a different plug than all the other cars. These are great horns and sound awesome! You will be very happy.

I drive a Mini Cooper and people don't see me so I need to be heard. 5 Super Loud! Posted by Josh Hamman on 12th Sep 2014 When my stock horn died we replaced them with a set of these. They are super loud and will make sure people notice when you use them. Had to cut a small piece of plastic on the bumper to make them fit, but well worth the effort.
