Well I got myself a pair of long bodied pliers and set about tackling the job
Job was made easier as the small cover had already been removed and not replaced by a previous owner.
Best way is to go in from the rear
Managed to pop the holder out dead easy,pulled the bulb out of the holder,another easy job.
Next,pop the new bulb back in the holder,dead easy...................
Not.............
Dropped the bulb which I can see in the battery tray
hands are far too big to get down to the tray
Brainwave.......
Put some sticky tape on the end of a long screwdriver and prod it so it sticks on that
Flicked the bulb even further and it's now sat on the tray but under the washer bottle pipe
Brainwave.......
Get hoover out and try to suction the bulb up the pipe
There are now small children and women running around the street screaming
"look at the madman hoovering his engine"
Bonnet now slammed and off to buy another bulb
