@TOKELLY posted:Sorry about that! I quickly searched for "buck-boost converter" without reading through the information. The other information is valid. In my own records I had links to all the devices I purchased, but not one link worked today; so I didn't copy any of them. I apologize.

Thank you Terry & John,
I will look closer at the pricing tomorrow, but it looks like about $7.00 per car… I guess that’s not too bad… though it might be hard to slip by the accountant. Terry, I had no trouble with the LED link to Amazon, 32.8 ft for $17.00 – looks like a good price.
I do have two questions: in the diagram there is something I interpret as a resistor (maybe the red rectangle is the choke?). What should the value be? And is the choke necessary, I don’t recall seeing them in other circuits, plus the Mouser is $3.11 if you buy 10. That’s about half the cost per car.
If the capacitor really doesn’t reduce the flickering, why add it?
As you can tell, I have no idea what each item contributes to the whole system.
Thank you for taking the time to look up the values,
