backlit korg thingies..

If anyone knows where i can pick up some of those backlit rubbery thingies used on the electribe sequencers and Mc 909 sequencers,or the rubbery pads on a korg microcontrol that light up would be great..looking to add mpc pads to the mix on my upcoming project…the new korg one seems to be bang for te buck..but im really up for building something to my own specs…TY in advance for the links if anyone knows on where to order would be greatly appreciated..
