Sink Project: Light Switch 01

Sink Project: Light Switch 01 is a holodisk in the Fallout: New Vegas add-on Old World Blues.

It contains the personality module for Light Switch 01, and is part of the All My Friends Have Off Switches quest.

Location
Upon entering the X-2 Transmitter Antenna Array, a desk can be seen along the southeast wall. The holodisk should be sitting on top of it, leaning against a coffee machine.
