Hello I will help you with your question,
The bulb procedures are below, do not touch the glass of the bulb with your fingers and to release the retaining spring you push in and down. It opens like a door.

And here as well
There is a tab on the bulb base that clocks the bulb in the housing, note where it is when you remove the old bulb
Look over these procedures and let me know how I can help you with this
This is specific to your Murano, If you have a problem with the procedure let me know where you are having difficulty so I can help you
Maybe a video will help, this shows replacing the headlights but it also shows the bulb replacement

Let me know if that helps you
The 03- 07 bulb replacement is the same procedure.
Look at the video and see how the cap is removed and the bulb is released. It is the same as yours.
You only need to remove the fender protector over the headlamp and then the cap can be turned. It is tight and you are working with your fingertips but it can be done.
Many autoparts stores will replace the bulb for you if you purchase it from them.
