Seat memory switch not illuminated?

Just noticed last night that the seat memory buttons are not illuminated on my Passat. Can anyone else chime in if theirs are?
Wondering if mine has a faulty bulb in it, as the memory buttons seem to work fine. I would expect these would be illuminated?
Thanks

Image of the buttons I am referring to on the left side of the drivers seat:
