I know one must add a resistor to the bulbs,which I have a pack of 1/4W 560Ohm Resistors,,,but after that,,what goes to what? I have a few units I want to do,,and have a successful Sound Install to a RTR SP Patched UP6210 but want to install Front,Rear,and Ditchlights (Which could option Flash) Any help,,or correct website steering is greatly appreciated.

But wired into decoders in general, including some using that 1.5 volt common, they don't seem to last long. I won't wire any more of them into locomotives. Pre-wired 402 or 603 surface mount LEDs are down to about 20 cents each now IIRC and I am happy with them.

I have some locos with many hours on them and are fine, but most bulbs fail within 10 hours or so of running. If you like the look of a bulb more than an LED, and I do prefer bulbs, at least for older power then you should get the Miniatronics 1.5v blubs, they are stated to last on average like 10,000 hours. I have not had one of them burn out. OH, and the Miniatronics bulbs are brighter than the ATH ones. All of this is why ATH switched to LED's.
