Puddle Lights Puzzle

[DSLiverpool]

I have this mirror, the puddle light bulbs have gone and I have read I slot a flat blade screwy into the bottom of the gap under the glass but its not happening for me - is my mirror a prise out holder or am I missing something obvious?
Ta

EDIT - whats missing on all the online guides is PUT YOUR SCREWDRIVER IN THE SLOT ie its not a fiddle about to get the tab - sussed it ;o)
