Changing low beam bulbs

[bprosperi]

I have an 06 mazdaspeed6 and can not see how to replace the bulb in my low beams. I removed the cap and unplugged the wire but stuck there. I have read a few things about removing a wire clip but I do not see a wire clip like they are showing. I see another black cap. Does this part just pull out or does it unscrew? Here is what I see:

Unscrew the black cap that's around the bulb base (the part that has all the numbers and letters on it). Your bulb should come free.
