Head light bulb removal

Hi all,

Hate doing this as my first post but is there something I should know about the headlight bulb replacement on a 03 1.2 HB Polo.

Have taken off the protective rubber cover on the driver side headlight and there is some movement in the bulb but I am afraid I am going to break the casing.

Is it just supposed to twist out or is there something else that needs to be done???

Thanks in advance
