You heard of Ringtones - now there are horntones
The Horntones FX-550 system is the first mobile audio system that allows you to customize the sound of your vehicle's horn function using virtually any standard audio file.
So if you made that stellar GPO, JABB or Strad demo - honk your horn to let the world hear it.
You can honk your own sound clip for a chase scene, one for a bucolic country ride, relaxing music for rush hour, and some hot music to impress the opposite .
I've been wanting to customize my jalopy with custom sounds for a long time and now it is possible.
