This is a rather old thread. The original posters may no longer be monitoring it.
Here is a screenshot of the example along with a LV8.5 VI.
Note there were 2 different concepts mentioned. One was toggling the value of the Boolean using Not and shift registers. The other mentioned was the blink property that controls and indicators can have. Actually 2 completely different concepts.

I'm also try to toggle an LED but I'm still having difficulty. I'm trying to illuminate a LED for 20 ms, every 1000 ms. Sounds simple doesnt it? Anyone have any advice on where to get started. I posted what I have so far but it seems to be running too fast.

Your inner loop has a problem in that it will run forever if a True comes into it. There is no way to change the value inside of it because it is defined at the tunnel.
You only need one while loop. You could store your wait time in another shift register and toggle between a 20msec wait and a 980 msec wait every time the boolean changes value.
