An apparatus is provided, which includes an electrolysis cell, a liquid flow path that passes through the electrolysis cell, and an indicator light. The indicator light is illuminated as a function of an operating characteristic of the electrolysis cell and luminous flux radiated from the light illuminates liquid along at least a portion of the flow path.

1. An apparatus comprising: an electrolysis cell;a liquid flow path that passes through the electrolysis cell;an indicator light arranged relative to the flow path such that luminous flux radiated from the light illuminates at least a portion of the flow path on the apparatus and is visually perceptible through liquid in the flow path from a viewpoint that is exterior to the apparatus; anda control circuit, which is configured to illuminate the indicator light as a function of whether electrical power is applied to the electrolysis cell and as a function of electrical current drawn by the electrolysis cell when the electrical power is applied. 2. The apparatus of claim 1, wherein the indicator light comprises: a first indicator light, which has a first color, wherein the control circuit is configured to turn the first indicator light on when the electrical current is within a first current range and off when the electrical current is outside the first current range; anda second indicator light, which has a second, different color, wherein the control circuit is configured to turn the second indicator light on when the electrical current is outside the first current range and off when the electrical current is within the first current range. 3. The apparatus of claim 1 and further comprising: a housing comprising a window that is at least translucent and through which at least a portion of the luminous flux radiates. 4. The apparatus of claim 1 and further comprising: a housing comprising a translucent portion through which at least a portion of the luminous flux radiates. 5. The apparatus of claim 1, wherein the liquid flow path comprises a container that is upstream of the electrolysis cell along the flow path and the indicator light is positioned to illuminate liquid within the container. 6. The apparatus of claim 1, wherein the apparatus comprises a hand-held spray bottle, which carries: the electrolysis cell;a pump coupled in the flow path;a container in the flow path for containing liquid to be treated by the electrolysis cell; anda nozzle in the flow path; anda switch, which has a first state in which the control circuit energizes the pump and the electrolysis cell and a second state in which the control circuit de-energizes the pump and the electrolysis cell, and wherein the control circuit enables illumination of the indicator light as a function of the electrical current drawn by the electrolysis cell when the switch is in the first state and disables the indicator light when the switch is in the second state. 7. The apparatus of claim 6, wherein the indicator light is positioned to illuminate liquid within the container. 8. The apparatus of claim 7, wherein at least a portion of the container is at least translucent. 9. The apparatus of claim 8, wherein the bottle further comprises a housing in which the container is located, wherein the housing comprises a portion that is at least translucent, through which at least a portion of the luminous flux within the container is visible from a viewpoint that is external to the housing. 10. The apparatus of claim 1, further comprising: a current sensor coupled to the electrolysis cell and having a sensed current output, which is fed back to the control circuit and is indicative of the electrical current drawn by the electrolysis cell. 11. A method comprising: carrying a liquid in a hand-held spray bottle;electrolyzing the liquid with an electrolysis cell carried by the bottle to produce electrolyzed liquid;dispensing the electrolyzed liquid;sensing electrical current drawn by the electrolysis cell when electrical power is applied to the electrolysis cell during the step of electrolyzing; andilluminating at least a portion of at least one of the liquid or the electrolyzed liquid with an indicator light as a function of a level of the electrical current sensed when electrical power is applied to the electrolysis cell, such that luminous flux radiated from the light is visually perceptible through the liquid or the electrolyzed liquid in the flow path on the bottle from a viewpoint that is exterior to the bottle. 12. A device comprising: a container;a switch having a first state and a second state;a nozzle;a liquid flow path extending from an interior of the container to the nozzle;an electrolysis cell in the flow path;a pump in the flow path, wherein the pump and the electrolysis cell are energized when the switch is in the first state and de-energized when the switch is in the second state; andan indicator light, which is positioned relative to illuminate at least at least a portion of the flow path on the bottle such that luminous flux radiated from the light is visually perceptible only through the portion of the flow path from a viewpoint that is exterior to the device;a current sensor coupled to sense electrical current drawn by the electrolysis cell when electrical power is applied to the electrolysis cell; anda control circuit, which is configured to enable illumination of the indicator light as a function of the sensed electrical current drawn by the electrolysis cell when the switch is in the first state and to disable illumination of the indicator light when the switch is in the second state. 13. The device of claim 12, wherein the device is a hand-held spray bottle. 14. The device of claim 12, wherein the indicator light comprises: a first indicator light, which has a first color, wherein the control circuit is configured to turn the first indicator light on when the electrical current is inside a first current range and off when the electrical current is outside the first current range; anda second indicator light, which has a second, different color, wherein the control circuit is configured to turn the second indicator light on when the electrical current is outside the first current range and off when the electrical current is inside the first current range. 15. The device of claim 12, wherein the indicator light is positioned such that luminous flux from the indicator light passes through liquid contained the container, upstream of the electrolysis cell.
