    Abstract: A system creates a desired current level within a traffic signal. A power supply unit receives an external power signal and transforms the power signal to a lamp current. A pulse generator monitors the value of the lamp current and automatically adjust the power usage of the current sink circuit to maintained a predefined current amplitude. A current pulser generates square current pulses at a frequency based at least in part on the frequency of the lamp current. A current sink superimposes the rectangular current pulse onto the lamp current and outputs a combined power signal to the alternating current power line.
