Mirror repeater bulb replacement

[Argos]

Hi Folks,
Anyone got the secret to replacing the repeater bulbs on the 2005 S40 door mirrors? Couldn't spot this in the manual, though it looks like it's a simple "prise it off" job. Thought I'd ask before I pop it off and wave goodbye as it launches itself off into next door's garden!
Thanks :)

first you must remove the mirror glass, this gives access to the indicator bulb, also the ground light bulb, if fitted.
