Light Switch 01

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

Background
The holotape to activate this station is found at the X-2 transmitter antenna array. Light Switch 01 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 argues with Light Switch 02.

Quests

 * All My Friends Have Off Switches: Light Switch 01 is one of the appliances you have to give the upgrade codes to.
 * Influencing People: The Smart Lights upgrade for Light Switch 01 must be found and installed.

Effects of player's actions

 * 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 lasts for up to twelve hours, or until 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.
 * The Courier can flatter it using the Cherchez La Femme or Lady Killer perks.

Appearances
Light Switch 01 appears only in the Fallout: New Vegas add-on Old World Blues.

Behind the scenes
Travis Stout wrote the light switches' dialogue.

Bugs
The "Smart Light" and "Mood Light" bonuses are applied to the player only when the player enter dialogue with the light switch and toggle such light. So, after the light is toggled, when the bonuses passes, just re-entering the Sink and be exposed to the light won't be enough to get the bonuses again.
 * In this case, to get again the bonuses of the light already toggled, it is needed to first toggle any other type of light (even normal light or lights off will work) and then toggle to the desired light again.
