Reply to "Passenger Trains and Mars Lights"

You wouldn't use any of those, the N8031 MARS Light Simulator is the one you want.  It needs a filtered DC power supply from 6V to 18V, preference being 12VDC or lower to avoid overheating the tiny regulator on the board.  If you are driving a red LED, then you want the N8031C version for the lower voltage red LED.

Thanks for the recommendation.   From your experience, and possibly with this K-Line car, are the marker lights & end light  using AC?     The filtered DC power supply has me a little confused, are you saying add an 18volt diode in series to convert AC into DC for the red light?    I will test the two leads to the red LED to read the Voltage.   Any other suggestions?

Thanks, Dave
