Reply to "New Legach SD40T-2 gyro lights"

I have 2 of these engines with the gyro lights in order to access the screen above you will need the newer version.  The full moon and half moon icon is the one that controls the gyro lights, but I do have to say these lights are typically always on, so I would conduct a reset of the engine and if they do not come on I suspect there is something wrong with the board that controls these lights, and having access to the screen above probably will not help you.
