Abstract
Abstract The self-contained diagnostic system is provided for a stroboscopic light circuit. The diagnostic system includes a plurality of signal lights, preferably LEDs, connected at various locations in the circuit to provide a visual indication of the faulty portion of the circuit in the event that the circuit does not operate properly. The system provides a quick and easy method for determining the location of a malfunction of a stroboscopic light without the necessity of replacing the entire light system or the use of diagnostic equipment.
