Reply to Nanokontrol led help

Ok I recieved a Nanokontrol in the post today that i won on Ebay the other evening . I'm planning on using this as part of a mod I'm doing.

I've just Fixed a broken usb socket and removed all the pots and faders which was straight forward enough. Next up I solder wires to the led's under each button But when i activate the button the led (green one) is too dim?

Does anybody know if it's possible to make it brighter somehow?
