Dreamcast Controller LED Mod?

[RC7]

I was wondering if it would be possible to wire in a LED or two inside a dreamcast controller. I think one or two bright blue or white leds would look really cool in side my translucent blue controller. The questions are: Is there available voltage? and, Where would you tap that voltage from? I know this is a pretty random thing, but people have a lot of random knowledge on this board. Thanks for you help in advance.

The only way to really know is if you open it up and test the wires with a voltmeter.
