Puck light dome cover to replace?

[Carolapf]

I am looking to replace the dome covers of the puck lights in the bunks of my Passport GT 2951. The little push buttons are already broken - little hands don't know how to work them.
The little soft button comes out and the ring in it gets lost. :facepalm:
Does anyone have an idea where I can get replacement covers?
