After you kill the four guys where you deliver the pizza (Ninja Turtles anyone?), there is a nice room with a couch(Badass Challenge) and a tv. There are five lights on the wall in the adjacent room. Once you turn all five lights green, a guy named “Flinter” jumps out and he drops some cool stuff. I got a blue revolver and some eridium.
To get all five lights green, you have hit the four items in the room: the lever, the valve, the tv, and the switch. They all have two positions. I have coded the lights on the screen shot below. The buttons change lights in the following patterns:
Lever – 1 & 3
or 4 & 5
Switch – 5
or 2 & 3 & 5
TV – 1
or 1 & 3 & 4
Pipe – 1 & 3 & 5
or 1 & 2
The main problem is the lack of one solution that always works. In my experience, the switches do not spawn in the same position for every person. This means that a “two clicks here, 3 clicks there” process doesn’t work. However you can, now knowing what each button does, solve the puzzle through a simple process.
Here is how it works. In an ideal world you would hit pipe, lever, lever, TV, and have green across the board. But if any of the buttons are in the wrong position, it doesn’t work. So start by hitting the pipe see what you get, (1,2) or (1,3,5). If you get (1,2) try for lever, lever, TV. If it works, great! If not, use the button descriptions above to slowly pick your way through the puzzle. Don’t be afraid to undo a move by pressing a button two more times. The knowledge of what the buttons do will speed up your solve time dramatically compared to guessing. At the same time it only takes a couple of minutes of random pushing to get the correct sequence. Watch out for Flinter when you get it right.
