If you're one of those people who can't stand the constant "beep-beep" of horn-happy motorists, you might not want to read any further. A start-up called Horntones is giving drivers the opportunity to customize their own car horn's output by using any MP3 file as their honk of choice.
Using a combination of Horntones' Web site and the company's flagship FX550 device, drivers can download any audio file they like (copyright issues notwithstanding) to use as their car's horn sound. The FX550 comes with 256MB of memory and nine preset buttons, giving horn-pimpers plenty of options for customization. The device also comes with a 150-watt amplifier and a pretty robust-looking speaker to ensure that other road users get your personalized message loud and clear. According to Mike Cosco, the brains behind Horntones, the FX550 is aimed--unsurprisingly--at 16- to 25-year-old drivers. It's on sale now for $299.
