Adding LED's to Locos

[liengineerbob]

I am looking to add some LED's as headlights and ditch lights on a few of the locomotive projects I am wrapping up.

My question is, do you need one resistor for each LED or will one resistor on the feed for all of them work?

I am not using DCC and do not have decoders installed, and more then likely they will never have decoders installed, so I am looking for a simple set up.

All the locos are straight DC.
