Now the answer to your question: why would the current rather flow through the Light Emitting Diodes rather than through the Collector Emitter path of the transistor?  is that in OFF state the transistor does NOT conduct current and the flyback pulse from the coil is able to forward bias the LED so that current can flow through the LED. 


So, the transistor is there specifically to agitate the coil and has little to do with the LED; I think I understand now.

I'll be refining my circuits as well as looking at that link you posted.

Thanks again for the information.

Is anyone familiar with the NTE brand transistors?  There is a retailer in town with a whole wall of products by this company.
