LED Reverse lighting
how ingenius
WOW! Never thought of this wiring diagram. I plan to wire engines simply in a square with polarity reversed. It automatically lights in direction traveling.TO continue, I made another little demo. This is two 3mm LEDs wired together at opposite poles with 1/4 watt 470 ohm resistor. This eliminates the need for a diode or bridge rectifier with AC current. The LEDs protect each other from the AC back current. So what happens is that both of them light up. If you had this with DC only one would light up and then the other would when you reversed the current
