Abstract
In some embodiments, a signal of light may be emitted from an illumination source of a first transceiver. A second transceiver may detect a signal of light from the first transceiver that exceeds a threshold luminosity; and activate, in response to the detecting of the signal of light that exceeds the threshold luminosity, an illumination source of the second transceiver to illuminate. An intensity of the illumination source of the first transceiver may then be reduced in response to the activating of the illumination source of the second transceiver to illuminate.
