So in theory if I hook up a 9 Leds in a parallel wont it just be enough? im confused because I used the LED calculator and it said if I hook up 32 Leds in parallel and each take 3.2 volts, I would only need a 20 ohms resistor.
As for the train interior, I was going to remove the incandescent blubs and just put in like 3 white Leds to make it look more brighter and prototypical. Last question, what did you use the cut the track? Thanks again!
