This is not a problem with the locomotive. This is a “consumer modification”, should you desire to have something other than “amber” classification lights. My railroad does not use “amber” or “red” classification lights. I also am fond of the color of actual incandescent bulbs for use in a model of a prototype that actually USED incandescent. Since I run strictly radio/battery, and favor 14.4v, I found many years ago that two 12V Grain-of-rice bulbs in series across 14.4V was just about perfect. This series of photos shows the original LED in place in the light base. Remove from smokebox front by removing front (pull out), unsoldering wires at board for each light, and pulling assembly straight out. The top lens housing lifts off, although it may need to be coaxed with a knife blade at the parting line.
I mounted my incandescent bulbs with a dab of hot glue. If you want to use LEDs, just bend a 90° at the base and insert into base.
I connected one leg of my series bulbs to the “+” LED pad on one side, where I removed the original LED. (far side of board in this photo)
The other end, as shown, connects to the “red” wire along the bottom of the smokebox board. (lower left in this photo)
I left my wires long as I will be removing the on-board electronics and re-wiring this locomotive to a much simpler arrangement. It is hard to get a good photo, but they are white:
Have fun!
