I am in the metro tunnel trying to get all four of those green lights to stay lit. I have tried everything and three will stay lit but not the fourth. What is the secret to this puzzle? Is there a certain place to put the glyphs? Someone help....Please. Thank-you midget

You can only do 3 at the most of the gauges to stay.
Try doing the console and the line you want to do.
Then do the console bit and power up the next one you need to do - console and another line.

By now doing 2 at a time is a breeze for you.

thank-you MaG, I am off and running again. Midget.

Don't trip and have fun!
