Unlike other USB cables which are only illuminated at the ends, Flash Pro cables are lit from end to end. A thin EL cable runs throughout the cable’s entire length, providing some pizazz in an otherwise boring, but necessary accessory. In addition to adding some eye candy to your desktop, there are useful advantages as well. LEDs in the cable ends immediately indicate that a proper connection has been made. With the entire cable illuminated, it is now easy to trace any given cable, to more easily connect and disconnect peripherals from your USB hub. And, since the cable flashes when data is transferred through it, you can easily determine if data is making it from point A to point B.
