Abstract
An indicator assembly for indicating the level of liquid in a tank includes one or more columns of lights that are turned on or off as the level of liquid in the tank rises and falls. The lights may be turned on and off by the passage of a magnetic float that changes the state of magnetically actuatable switches, such as Hall effect transistors, that are associated in a one-to-one relationship with the lights. If two columns of lights are used, they may be of different colors.
