Hello,
i need a source of 3 volt on my wireless controller, for lightning the A,B,X,Y buttons. I cant find a source witch the led´s are off when the controller also is of. And when i turn the controller on the lights also turn on.

I hope you understand what i mean than my english is not so good.

Thanxs a lot!

This has been covered tons of times. The only 3v source (3v only on a fully charged battery pack) is off the headset pins. There is no source that turns on and off with the controller. You'll have to wire up a transistor and a couple resistors ($.75 in parts from Radio Shack or free from old electronics).

what for a transistor i need for them??

The led´s i want too use have 3 volt, so i dont need resistors for them.

at wich points i must solder the pins from the resistor??

thanxs a lot!
