Hey Tetters. Looks like your learning alot with this one.Yes a 1 K resistor will work.I have dwarf signals on my small switching layout with power taken from the bus at 14 volts.They are LEDs and they work good with a 1 K.I didnt relise it was a drop in for another loco or I would have told you the same thing .At least you didnt have to remove the shrink wrap on it to find the output.
