Lights may soon do more than just shine in dark places – they might wirelessly connect your computer, phone or car to the Internet.

"We can provide ubiquitous communication if we have network access wherever there's lighting," said Thomas Little, a computer engineer at Boston University.
These aren't just any lights, though. Little and other researchers hope to piggyback on the spread of light-emitting diode (LED) light bulbs, which are finding favor as low-energy, long-lasting alternatives to the more conventional incandescent or fluorescent light bulbs.
