Is this what I need for a MTH Railking 2-8-0:
The 2-8-0 in question is now powered by Battery-Powered RC (BPRC) with a 9.6 vdc NiMH battery pack using a Tx7k transmitter and ALPHA 3v2 Rx w/onboard ESC
The Evans site says these are equipped with dropping resistor so it seems all I need to do is disconnect the 2 bulbs I used and connect the LEDs in their places.
