What is the LED board for?

The XPS 13 laptop has an LED board in it. The board plugs into the motherboard, but it's not really clear to me what's for. The board is pictured here, www.ebay.com/.../262105473513

It holds the system LEDs -- charging, power, etc.  They're on the front edge of the palmrest in this model.
