THERE ARE FOUR LIGHTS!
Star Trek: The Next Generation - "Chain of Command, Part II"
In this episode Captain Picard is interrogated/tortured by a Cardassian named Gul Madred. As part of the sessions, Madred asks Picard how many lights there are. Every time Picard answers correctly that there are four, Madred insists there are 5. At the end of the episode when Picard is released and after sucessfully resiting many sessions with Gul Madred, he shouts to him that "THERE ARE FOUR LIGHTS!"
The connection with this cache? As soon as I pulled up and spotted this site, it was the first thing that popped into my head. Call me a SciFi geek if you will, I resemble that remark 
Also reminds me of some of my SERE training...Return with Honor! Happy 50th Anniversary!
Congrats to GeopenguinsH for the FTF!
