foregoing operation of the plurality of indicia 120 a 120 b 120 c and 120 d and associated light tubes 125 a 125 b 125 c and 125 d to graphically display the liquid level in the carafe 105 of beverage vessel assembly 4 is illustrated in fig5 and 6 as can be seen in fig6 the liquid level in the carafe 105 of beverage vessel assembly 4 is at the half full u00bd level meaning the liquid level is at or above the height of the light tubes 125 c and 125 d as a result light entering the light tubes 125 c and 125 d through their first end is absorbed into the liquid below and indicia 120 c and 120 d are seen as darkened or unclear indicating that the carafe 105 is at least at the half full liquid level oppositely light entering the light tubes 125 a and 125 b through the first end is reflected back through and out of the light tubes 125 a and 125 b through their first ends such that indicia 120 a and 120 b are seen as darkened or unclear indicating that the carafe 105 is below at least the full and three quarters full u00be liquid levels with little reasoning it is obvious that the carafe 105 is at the half full liquid.
