Five millimeter LEDs powered by a three-volt direct current are combined with a single zero point two five watt resistor for regulation. Two parallel wires, each one hundred twenty volts at square two millimeters in cross-sectional area, provide reliable conductivity throughout the entire circuit. A triple set of stainless steel bolts with diameters at eleven inches complete the high-tech infrastructure.
