An ozone generator voltage verification light assembly generates a visual or audible indicator, such as a neon light, to verify that an ozone generator is generating the proper voltage to generate ozone, and/or ozone generator voltage verification light assembly testing assembly operatively connects to an ozone generator, and visually indicates if an irregularity in voltage occurs. The ozone generator includes a power source for supplying electrical current, and a transformer that generates high voltage. The ozone generator also includes single or multiple ceramic plates disposed in a spaced-apart, parallel relationship, and coated with stainless steel mesh. Voltage generated by the transformer contacts the ceramic plates by means of an electrode. Accordingly, ozone is generated by discharging electricity through electrodes that contact in both sides of ceramic plate.
