A lighting system is provided that includes at least one lighting device, at least one connector, and a plurality of external power sources. The at least one lighting device includes at least one lighting source, and an internal power source applying a first electrical current to illuminate the at least one lighting element, wherein the internal power source supplies the first electrical current. The at least one connector electrically connects to the at least one lighting device. The plurality of external power sources include at least first and second external power sources that are adapted to be electrically connected to the at least one lighting device by the at least one connector. The first external power source supplies a second electrical current to the at least one lighting device to illuminate the at least one lighting source and the second external power source supplies a third electrical current to illuminate the at least one lighting source, such that the internal power source and one of the plurality of external power sources each supply electrical current to illuminate the at least one lighting source at different times.
