Wiring A Light
When you're building a model, you want it to be as close to the real
device as you can get, but sometimes you need to add a little something
to the kit in order to get it the rest of the way there. LED lights, for
example, can make a car or train closer to perfection by mimicking
lights on the real machines. How you add these lights may differ from
model to model, but the theory is important to understand.
Examine your model to determine how many LEDs you want, and where you
are going to attach the LEDs, battery, switch and resistor. You can mark
these with tape or a marker.
