I don't have my Reader yet but I started by modifying my clip-on light. It is the 3 LED Booklight with the two light levels (check 2 posts back).
Well....now I have four light levels:
I placed a diode with a bypass switch to drop the voltage on the chip from 6Volts to 5,4Volts and it works great!
I also cut out the external holder so you can still fold the booklight.
Well, I think it looks good.
Now...if I were only to receive my precious toy.
