For the front dome lights, there are many versions and so you have to figure out which one you have.
I believe for NAR MK7.5, due to cost cutting, the front dome light buttons are not illuminated and VW made a different design than its Euro counter parts with slightly different circuitry. The LEDs can be swapped out however the stock LED have a bend to it because it's intended to be illuminated at an angle. So even if you swap it with a different LED, chances it won't have a bend to it. It also won't line up with the cover.

For Euro versions and early NAR MK7, the LED is soldered onto a small circuit board so as said in my post above, you'll need to modify it with a soldering iron.
