The image shows a control panel with three identical control units. Each unit has a colored indicator light at the top and a control lever at the bottom that can be moved to three positions (left, middle, or right). Each control unit has its own single indicator light, whose color is determined solely by that unit's lever position.

Observe the current control panel to infer the relationship between lever positions and light colors. Based on this inferred relationship, adjust the levers that need to be changed to make all indicator lights show blue color. Only modify what the task requires; keep the background and any other element unchanged. Process the levers from left to right and output one image after each single lever move.
