An intubation instrument includes a proximal end and a distal end, a handle positioned at the proximal end, a control interface disposed on or proximate to the handle, the control interface being configured to receive user input and to control a function of the instrument based on said user input, the control interface having a light source disposed within the control interface to illuminate at least a portion of the control interface, the light source alternately emitting light in different colors, each color indicating a different state of the function of the instrument. The instrument includes an imaging system for generating image data, and a monitor for displaying the image data and a graphical interface. A section of the graphical interface includes information about the state of the instrument and is displayed in a color corresponding to the color of light emitted by the light source of the control interface.
