Abstract
A material storage bin has an upright wall supporting a plurality of vertically spaced indicators providing a person with visual information regarding the level of the material in the bin. The indicators have contrasting visual colors as bright yellow and dark black surfaces that are selectively displayed to provide a person with information of the level of material in the bin. An actuator located in the bin cooperates with a motion transmission apparatus to move visual members to an ON position displaying the bright color when the material engages the actuator and to an OFF position when the actuator is free of material in the bin.
