A power energy supply system includes a power generating device, at least one ultracapacitor, and an electronic control module for supplying power energy to electric loads coupled to a vehicle circuit system under control of the ECM. Also a light emitting layer in the form of a mix layer contains a specific coumarin derivative, a specific quinacridone compound or a specific styryl amine compound. The respective insulating material discs are located between and fixed by the insulating bodies. Electrical signals are coupled into the resonating circuits by an encased signal coupler which is removably mounted by a coupling housing for supporting the signal coupler at the proximal end of the filter case for positioning in the vicinity of the resonating circuits.
