Abstract
A system for indicating a fluid level in a fluid tank of a machine includes a plurality of lighting units and at least one indicia. The lighting units are sequentially arranged with respect to each other and configured to be sequentially activated or sequentially deactivated to correspondingly indicate a real-time level of a fluid in the fluid tank. The indicia is disposed along the lighting units to correspondingly indicate at least one threshold level of the fluid in the fluid tank. The indicia allows inference of the real-time level to recede below the at least one threshold level if a sequential deactivation of the lighting units moves past the indicia in a first direction. In addition, the indicia allows inference of the real-time level to exceed the at least one threshold level if a sequential activation of the lighting units moves past the indicia in a second direction.
