I just realized something...... remember how you said there were no screws for the voltage selector switch?
I thought at first, all the screws were put in the holes they came from on the inside of the box.....

Maybe you can switch the volt selector back to the battery compartment and put my new switch for the LEDs into the spot that faces out the back of the box
. You wouldn't even be able to tell it was added!
See the two screws on the right side of your picture?
Here is the original:
