After some trip last fall, I noticed an oval hole
in my Vitrifrigo light lens:

Gives it a nice Victorian look, don't you think?  ;-)

All I can think of is that I left the fridge door open
after cleaning up at the end of a trip and the fridge
still had 115V power, the light stays on a long time,
and....  Vitri owners: you have been warned.
