Light Switch 02

Light Switch 02 is an artificial personality operating in the Big MT in 2281.

Background
Light Switch 02 makes innuendos and comments on the player's decisions. It argues with Light Switch 01, referring to it as "that frigid little ice queen."

Quests

 * All My Friends Have Off Switches: Light Switch 02 is one of the appliances one must give the upgrade codes. Its codes are found in Big MT north tunnel, leaning on a toolbox in the room to the right.
 * Influencing People: The Mood Lights upgrade for Light Switch 02 must be found and installed.

Effects of player's actions

 * Once the upgrade module is retrieved, Light Switch 02 can bathe the Courier in "Mood Light," increasing their Charisma by 2 points, and their Speech and Barter skills by 5 points each. The effect lasts for 12 hours after initial exposure, or until Light Switch 01's "Smart Lights" are activated.
 * 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 her using the Cherchez La Femme or Lady Killer perks, resulting in receiving a Meeting People magazine.

Appearances
Light Switch 02 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 character only when one enters dialogue with the light switch and toggles such light. So, after the light is toggled, when the bonuses passes, just re-entering the Sink and be exposed to the light will not 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.
