1. A water treatment system comprising:

  • a light source chamber;

    a light source within the chamber, the light source having a resistance;

    a moisture-detecting device within the chamber, the device electrically connected in parallel with the light source and having a first resistance greater than the resistance of the light source when a preselected level of moisture is not present, the device having a second resistance less than the resistance of the light source when the preselected level of moisture is present; and

    a control circuit operatively connected to the light source and to the moisture-detecting device, wherein the moisture-detecting device provides a relatively low resistance pathway preventing the light source from receiving power when the preselected level of moisture is present.
