( b ) the intended device combines the features of separate devices ( electrical transformers and portable lighting ) into one device . combined , these features offer a higher level of safety and convenience than what is currently available . an example of this would be the ability to locate and illuminate a receptacle in a darkened area using just the illuminated electrical transformer . ( c ) by illuminating the receptacle , a user can see to accurately align and safely insert the transformer . ( d ) the illuminating module can use a low power light emitting diode so the battery will have a very long run time . when the battery eventually does fail , the user can easily replace the dead battery and restore the entire unit to new condition . ( e ) the illuminated electrical transformer can utilize a recharging circuit that will keep the battery recharged , enabling an even greater battery life expectancy . situations where battery life may be shortened by constant use can benefit from this charging configuration . accordingly , the reader will see that , compared to using a standard transformer or power supply , my illuminated electrical transformer can provide a user with an unobtrusive and inexpensive means to more safely and easily perform this very common , everyday task of plugging an electrical transformer into a receptacle . furthermore , my illuminated electrical transformer / power supply provides additional advantages in that : ( a ) the present invention enables a user to easily locate a receptacle in a completely dark environment . ( b ) the present invention is designed to be , optionally used with conventional electrical transformers thereby allowing use of the illumination module on any transformer or power supply . ( d ) the present invention and additional embodiments enable user to provide to a variety of electrical transformers , an affordable , temporary and quick conversion from non - illuminated to illuminated . although the description above contains many specificities , these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments . thus the scope of the invention should be determined by the appended claims and their legal equivalents , rather than by the examples given .
