2006 headlight removal

[Maggadog]

I have been looking (yes, I used the search function) for a 2006 specific, remove and replace the headlight bulbs.
The only thing I have found does not match what I see when I look under the hood of my car.

It looks like the only thing holding in the headlight assembly is a metal retaining ring at the back end. I'm guessing if I use a flathead screwdriver to lift this up the assembly should slide forward, and at some point, I should be able to remove the electronics associated with the headlight.

Oh, great and wise auto wrenchers, does this sound reasonable to you?

I've never seen a 2006 headlight assembly; got a cam?
