A safe method is to simply use a DPDT switch from Radio Shack and a 9 volt battery ignoring the power pin altogether. Hook up the competition port pins to one side of the switch and an LED/resistor/9volt to the isolated DPDT pins on the other side of the switch. When the switch is "on" the LED will also be "on", but the LED is actually on a separate circuit powered by the 9v battery.
This is probably the normal method most teams use for LEDs on the OI.
