I am installing Tortoise machines on my layout and will start a panel using DPDT switches to change the turnout position. I would like to add bi-color led's (red/green) to the panel and power them using the contacts on the Tortoise. Could someone show me a simple way to wire these.
LED's have the following specifications: Forward voltage (R/G): 2.0/2.2 Max: 2.5/2.6 Reverse voltage: 5.0 Peak forward current: 150mA Steady Current: 25mA Given that the Tortoise uses 12V, I am assuming that I need resistors to not damage the LED but I don't know what value or how many are needed.
Any help would be greatly appreciated! I have very little experience doing this. Thanks!
