Any idea how to get the blown bulb out of the holder on the interior-light (the one with two map lights)?

Also, says 20 sec delay but mine just goes off when i shut the door

 

you are missing the yellow 20s delay relay from your fusebox to get the light to stay on, the maplight bulbs are fiddly and do involve pulling the back of the light unit apart to get to them unlike the central bulb which is easy

 

Thanks Steve..wish the chap selling had bothered to check if I needed the relay
