Tools required: Small flat bladed screwdriver & 2 Credit Cards - best to use old/free cards as they may get damaged. I used some readily available from Texaco


Simply slide the cards down either side of the rotary switch to disable the locking pins...



Pull/prise the entire housing forward and remove...



Bulb is located via the back and is removed with a small flat screwdriver, this is the grey piece in the pic ...



Once unlocked the bulb will simply fall out ...



Bulb markings are : ALBA 12V 0.5W

To refit, simply replace the new bulb and slide the housing back into it's holder.
