Since no one esle has answered, that LED would have a built resistor (or something) as most LEDs max at about 5vdc. Dcc puts about 12 volts into the rails as usable power. The voltage may appear higher than that with a VOM, but that's due to the pulse and bipolar nature of the signal on the track. As to it being "the right" part only the author could answer that for sure, but it appears to me that it most likely is. FRED
