The nightlights come with a 1/4 inch piece of plastic in them. It is not laser-able.
I replace that with two 1/8 (medium proofgrade) pieces of acrylic with a thin veneer of wood sandwiched between them.
It all fits together well, as long as you have the bottom of the pieces cut appropriately to be held in alignment with each other by the nightlight.
For more information on that, check out this post by marmak3261.
