Facelifted 2014 E350 Front Turn Signal Bulb LED Fitment

The turn signal bulb in question is the one with the white holder, I have tried twisting turning with significant force, but the bulb holder just wont move. I don't want to break it and have to replace the entire headlight assembly, is there a method to get this bulb out?
Also what kind of bulb is it? Some people are saying its a either a
-3156 or 7440
I'm considering getting these ones as they claim they don't need a resistor and don't throw any codes.
