Light Switch 01 is an artificial personality operating in the Big MT in 2281.
The light switch was used by Dr Mobius to research the ability of light levels to enhance human cognition. Once the doctor discovered that certain spectra of visible light actually increased cognitive function and reasoning ability, he programmed the switch with a routine that allowed for this spectrum to be activated across the Sink - and in a fit of seeming irony, programmed the switch's personality to detest Light Switch 02. When Mobius cut his ties with the Think Tank, the switch's holotapes were scattered at the X-2 transmitter antenna array (core OS) and the X-12 Research Center.
