LED lighting has become ubiquitous. Somewhere around half of all U.S. households use LED replacement bulbs for most or all of their indoor lighting, and LEDs represent an ever-growing share of the OE automotive lighting market.

Due to their principle of operation, LEDs are also capable of being switched on and off very rapidly – far more rapidly than the human eye can detect. This property effectively allows any LED used for illumination to be made into a data transmitter in a way that is completely imperceptible.

You may have heard a similar pitch before; so-called “Li-Fi” functions in much the same way, using infrared light emitters instead of visible spectrum LEDs to transmit data wirelessly. But where our implementation differs is that outdoor operation was a consideration from the very beginning.
