I took a few electronics classes in high school and college, and if I remember right, they have transistor chips that will invert the charge so if you get 2 of those, they should have 4-6 input/outputs plus the positive and negative connectors. If you get one of these, spend the time and energy to set up a circuit board with these proper connectors, then set up the LED's wherever you want them, it should work!. you could also do it a lot more simply by installing the leds like you want, then all you really need to do is to look at the light that is off... that would be the position. You also could look at one of the stickys here and do the clock thingy...
that would work for me..
If I were smart enough I guess I could set up an led indicator light system then sell them... lol.
Either way Good luck! and let us know what you end up doing.
