I have been adding lights to all of my Cabooses. Running DCC, installed two axles for pick up, but still get a lot of flicker. I did three interior incandescent in series to get a softer glow, and Aristo lanterns that must have LED's. Does any one have a diagram and component ratings to add a capacitor for some power storage, I also understand a resistor to limit a surge when powering up. Thanks for some help.
