Abstract
Abstract An electrical power extension cord having an illuminated connecting body at an end of the extension cord is described. The end is illuminated if it is connected to an active power source with or without a functioning ground conductor, depending upon the electrical configuration within the body. The body is formed from a translucent material having the illumination apparatus embedded within such that the illuminated body is visible from all directions.
