Thought this would be simple but looking at it and it doesnt look very simple...what am I missing?

 

That is pretty simple. I just put in the intense blue halogens in my Z. All you do is twist the bulb plug one way or the other, and its out. Then remove old bulb, and replace it with new one. Be careful to not touch the bub itself, the glass part, for it supposedly shortens bulb life. Have fun.
