I selected the Richmond Controls Golden White LED for the rear
to have a color balance with their SMD LED in the headlight.
Once the LED and resistor are in place, I use a 9-volt battery
to test for operation. With one polarity, the LED should light.
With the opposite polarity, it should be dark. Note or mark the
tab that is connected to the positive battery lead when the LED
lights (12).
Install about 6 inches of blue wire to the tab that was positive
when the LED lit. Install about 6 inches of yellow wire on the
other tab. I used the 30 AWG wire from TCS.
Route the wires out through the gray plastic holder (12). Save
this assembly for use when the loco is put back together.
3.2 Front light
I selected a Richmond Controls Golden White SMD LED for the
front light, as it saves valuable room inside the loco. Now is the
time to install that LED, so that the glue can dry. Richmond sells
