Getting blank out
Once you've sourced your bulbs, you can get on with modifing the blank.
To get it out, you need to undo 3 torx screws. IIRC they are torx 5.
The blank/holder then comes out.
Take it to your work bench and screw it down (not to tightly as the plastic breaks easy)
This makes it easier to remove the plastic dome.
Use a small HSS bit, 2 or 3mm to make a pilot hole.
Then using 45mm saw bit, drill out the center part of the plastic.
You should have a clean cut hole, that shouldnt need any further work.
