The purpose of this project is to develop a timing light circuit capable of using a light emitting diode. With the incandescent light bulb no longer being produced, there is a demand for a timing light capable of using an LED. The trouble with using an LED in place of an incandescent bulb is its inability to emit light when exposed to the low or negative voltages. This issue is addressed using a full wave rectifier and introducing a biasing voltage. The LED timing light will have the same behavior as the conventional timing light timing light. The timing light increases in brightness as the phase angle between two sinusoidal voltage sources deviates from zero degrees. For example, it can be used to ensure a generator and power grid frequencies and timing are in sync before being electrically connected. This LED timing light was developed for an energy systems lab where the lights are used to synchronize a three phase synchronous generator to a large stable system which is essential in ensuring the stability of any power grid.
