Thanks to the work of @NUKDDD and this wonderful work he shared with us, I now have a few Felixes in my house. 

But since I don't really need to have them turned on at the same time and it was inconvenient to unscrew the caps every time in order to switch the tealights on/off I created this pill shaped casing for the tealight, allowing them to slide perfectly through the bottom of the mushroom.

Enjoy!
