now im getting the grip on modding,...here is my keyboard light for this mod i used 3 1.5v aa batteries and 2 maybe 2 volts lightdiods...dunno how many volts here is a picture: http://img53.exs.cx/my.php?loc=img53&image=keyboardlight6bo.jpg
Looks like christmas to me I wouldn't use batteries, LEDs suck a lot of current for a battery. I would have made small enclosures for the LEDs to hide the back leads and wires, and they would run straight into the keyboard where there's a 5 volt line.
