What are you talking about?  Do you mean you want to have one LED brighten and dim?

If i remember correctly, that LED with the broken leads are optional.  Meaning, if you want more than one LED, you have to wire them in parallel, as the schem suggests.  If you want just one LED, just disregard the one on the right.

I'm just want one LED to brighten and dim in a half second intervals. I kinda see what you are saying about the LEDs on the right. Thing I want to do is have one LED pulsing and my HDD meter Light up around it in a circle so it looks like a gauge.

Just remove either the NPN or PNP transistor and the associated resistors and diodes.
