Athearn Genesis SD70

yes.

That is exactly how I was going to do it, except I don't use flashing ditch lights so I was just going to use one resistor for each pair. Would the 820 ohm work for that?

I use a 820 ohm resistor for each ditchlight bulb, because of the flashing feature, and one for each headlight pair, but I leave the headlights wired in parallel, with one lead from each lamp connected to the resistor,

Why in series?

I have a pair of Athearn Genesis SD70s in HO, and installed my standard NCE D13SRJ in them, (They arent DCC Ready) But I need a resister for the lights. I called Athearn and they told me that they are 1.5v 15mA and I have them paired, (i.e. the 2 ditch lights, 2 nose lights, 2 rear lights) and I need resistors for each one. What would be the best one to use.... I am still REALLY confused when it comes to lighting and resistors......
