Yes, you need a dropping resistor. And also a polarity device. There are different ways to do this depending on if you use dcc or dc. Experiment with red leds at fifty cents versus $5 for a white one. I still use lightbulbs because white leds are more trouble than they are worth, cost way too much, and are not really white, but bluish white... I have a white LED flshlight and it is really nice, is bright, light,and easy on AA batteries. But they are too complex and costly for any benefit as a loco headlight.
