Cordless LED light driving wall module and night light

A fiber optic illumination device comprising:

• a light source for connection to an electrical energy source;
• a circuit electrically connected to said electrical energy source for providing DC voltage to said light source, wherein said DC voltage is in the range selected from 2.0 to 4.0 Volts;
• said light source comprising at least one Light Emitting Diode (“L.E.D.”) powered by the DC voltage;
• at least one fiber optic cable for selectively connecting to said light source, said at least one fiber optic cable having a light input end and an opposite light output end, and further being adapted to selectively emit light radially from a lateral surface or axially from said light output end thereof
• wherein further at least a portion of said fiber optic cable is installed within a conduit carrying liquid for illuminating the liquid
• wherein further said at least one L. E. D. is multi-color and,
• a color control means for controlling the color of said multi-color L.E.D;
• a filter condition sensing means for sensing the condition of a filter in fluid communication with the liquid in said conduit;
• wherein said color control means changes the color of said at least one L.E.D. when at least one condition sensed by said filter condition sensing means changes, thereby changing the color of the light illuminating the liquid.
