What is your experience with Passenger car lighting keep alives? I see lots of circuit designs online but am not sure which one to use. I'm in N scale.
Well I guess I would say they all work. The trick if you are on DCC power you need a rectifier then a buck convertor or regulator then a resistor/s (or potentiometer) and some sort of capacitor or capacitor bank. Possibilities depend on how much room you have and how much you want to spend. How much you are willing to DIY, etc.. https://model-railroad-hobbyist.com/node/22380 A good article here.
Thanks. I actually decided to go with the N Scale lighting method in MRH's Feb 2019 issue using the three bulb cut length LED strip method. Parts ordered, just waiting for them to arrive.
