A light-transmitting subsystem can include an LED light source including a first to LED light to emit a first wavelength of light with a first center-emission wavelength and a second LED light to emit a second wavelength of light with a second center-emission wavelength that is offset from the first center-emission wavelength. The system can include a first reference oscillator to receive a reference signal from a remote or broadcasting source, and can also include a synchronous modulation and power system to convert the reference signal from a synchronous relative high frequency signal to a synchronous relative low frequency signal and provide synchronized power pulses to the first LED light and the second LED light in synchronous correlation with the synchronous relative low frequency signal to generate a stream of modulated light-signal pulses which includes a first modulated wavelength of light and a second modulated wavelength of light.
