Abstract

An improved fluid level verification apparatus with an integral, internal source of illumination that is powered by an integral, internal energy source and is activated by a motion sensor or any other sensor commonly known in the art to detect the presence of a person in dark or dimly lit environments. The preferred light source is a light emitting diode (LED). A second embodiment of the integral, internal source of illumination that is powered by an integral, internal energy source and is activated by a motion sensor or any other sensor commonly known in the art to detect the presence of a person in dark or dimly lit environments is applied to a fluid reservoir tank.
