So over the weekend I was planning on replacing the lights bulbs that are located behind the instrument panel. I know the dial in the middle needs some persuasion with a screw driver but looking at the how to thread the other 2 should just pull off. I have tried pulling them off and used a bit of leverage with a screwdriver but they don't seem to budge, I don't wanna break anything. Any suggestions?

Mine took a while but give some brute force :p

Guess I'm just a bit worried they may be glued on?

They won't be glued on pal, just clicked on and need a good pull to get them off
