APPARATUS WITH electrolysis cell and indicator lights are illuminated LIQUID

摘要

An apparatus (10, 400, 500, 500', 700, 800, 980) is provided, which includes an electrolysis cell (18, 50, 80, 406, 552, 708, 804), a liquid flow path that passes through the electrolysis cell (18, 50, 80, 406, 552, 708, 804), and an indicator light (414, 416, 594, 596). The indicator light (414, 416, 594, 596) is illuminated as a function of an operating characteristic of the electrolysis cell (18, 50, 80, 406, 552, 708, 804) and luminous flux (522) radiated from the light (414, 416, 594, 596) illuminates liquid along at least a portion of the flow path.
