Example methods and systems to indicate the status of door operations are disclosed. An example door system includes a door panel having a leading edge to be moved in a travel direction between an open position and a closed position relative to the doorframe. The door panel to block the passageway when the leading edge is at the closed position. The door panel to unblock the passageway when the leading edge is at the open position. The example door system also includes a series of lights distributed along the travel direction proximate the doorframe. The example door system further includes a controller to switch the lights between a first state and a second state to provide a visual effect of movement corresponding to the operating status of the door system.
