Oh.. well.. That's very sweet of you. Maybe one of these nights we can 'discuss theorems.

Light Switch 01 is an automated personality operating in the Big MT in 2281.


The holotape to activate this station can be found in the X-2 transmitter antenna array. Light Switch 01 speaks to the player intelligently, but in a seductive tone. She makes innuendos and comments on the player's decisions. The Light Switch 01 Upgrade: Smart Lights can be found on the bottom most level of the X-12 research center leaning against a projecting unit. It appears to be in a conflict with Light Switch 02.

Effects of player's actionsEdit

  • After retrieving the upgrade module for Light Switch 01, the switch can bathe the Courier in "Smart Light", effectively increasing their Intelligence by 2, and their Science and Repair skills by 5 points each. This effect will linger for up to twelve hours, or unless the player activates the "Mood Lights" controlled by Light Switch 02.
  • Without the upgrade module, it is only possible to use the light switch to toggle the normal lights while the Personality Matrices are toggled off at the Sink CIU.

Other interactionsEdit


There was a dialogue option for Light Switch 01, acknowledging that the smart lights upgrade were found, but it is not present in the game.

Notable quotesEdit

  • "Unlike certain other lightswitches, I'm competent, I'd just love to turn those lights on for you."
  • "Have you been poking at the other light switch? You know she's riddled with virii don't you?"
