All,
Got a K4 4-6-2 steam loco #3750. Spectrum item no 84101. Year 2010. Light is out. Suspect it is the decoder.
Does this loco have the incandescent bulb or LED?

If it's the pre-war K4 the headlight is still available from the parts dept:

Len,
Changed out the decoder and light came on. Usina 1K ohm resister on the white wire. Guessing it is an LED. Thanks anyway.
