System for indicating fluid level in fluid tanks of machines

A machine, comprising:

• a fluid tank;
• and
• a system for indicating a fluid level in the fluid tank, the system including:
• a plurality of lighting units 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;
• at least one indicia disposed along the plurality of lighting units to correspondingly indicate at least one threshold level of the fluid in the fluid tank;
• and
• a headlight of the machine that is separate from the plurality of lighting units and from the at least one indicia, wherein:
• the at least one indicia allows inference of the real-time level to recede below the at least one threshold level if a sequential deactivation of the plurality of lighting units moves past the at least one indicia in a first direction,
• the at least one indicia allows inference of the real-time level to exceed the at least one threshold level if a sequential activation of the plurality of lighting units moves past the at least one indicia in a second direction,
• the at least one indicia is interposed between, and is adjacent to, first and second lighting units of the plurality of lighting units,
• the at least one indicia is configured to emit light having a first attribute,
• the first and second lighting units are configured to emit light having a shared second attribute different from the first attribute,
• activation of the headlight causes a decrease in a brightness of light emitted by the plurality of lighting units, and
• deactivation of the headlight causes an increase in the brightness of light emitted by the plurality of lighting units.
