DC travels one way, out of the battery at the positive pole, thru the resistor and LED and back to the negative pole.
Use a 9 Volt battery.
Pick up your resistors at Rshack and make a note of the milliamp.
to choose the resistors.
glue a piece of velcro to the battery and a piece to the bottom of the car.
Pick up a nine volt battery cap with leads at Rshack.
The longest leg on the LED is the positive.
Put the resistor in line on the positive lead between the battery and the LED. Doesn't matter which direction the color bands are.
Simply unplug the lead off the battery to shut down, or make a harness or..................????
Build up a prototype on the bench and play around a little until you get the desired effect.
I have reached the age where my train of thought often leaves the station without me....
