So my next project was to upgrade the 6-18981 conventional speeder.  Upgrade has gone well.  I ordered some flashing LEDs to replace the blinking gow bulb.  When I connect the flashing LED to the light output of the Mini Commander, it does not flash.  When I connect the LED to a Cr2032 battery, it flashes as expected.  In my circuit off the lighting output, I have a 470 ohm resistor and a diode.  I combined both the front and rear light outputs together with diodes so the light will always light, regardless of direction.

What am I missing for the LED to get it to work correctly?

Thanks

Bruce,

I think you may be on to something.  I went back to the site where I bought the animated LEDs and they seem to indicate that it requires pure DC power.  For grins, I made a quick bridge rectifier out of 4 diodes.  Connected to my transformer, added a resistor and my LED now flashes from track power.  So I guess that would work.  But I am wondering if the half wave power from the mini commander can be converted to pure DC power.  I was reading online that the addition of a cap across the leads of the LED could clean up the half wave power.  The question would then be, what size cap do I try.  Adding a cap to the lighting output would be easier than adding a full bridge.  The speeder does not have a lot of room, so less components is preferred.
