At first glance this appears to be an ordinary A to micro B USB cable. Plug it in to your device and power supply, and you get a colorful glitter of dozens of little LEDs embedded in the length of the cable. Suggest adaptation
Can be used for data and charging.
The LEDs are luminous but not too bright. Perfect for vampire makers, candy ravers, or maybe night owls who misplace their devices in the thick of night!
