Firstly if you dont have a short stubby pozzi screw driver or a driver with a flexi shaft you might find it easier to take the wheel off (no im not joking!)
if you can get a stubby driver stick the wheel on full lock to make access possible.....

now undo the 2 screws and remove the plastic panel....

now have a look inside the bumper you will see the back of the indicator...

Reach in and undo 1/4 turn or so anti clockwise *(you will feel the bulb holder release)*


then pull it out carefully towards you......

once you have hold of it remove the bulb press down slightly and turn anti clockwise and it will come out
refit the new bulb and put back together....
the bulb is an amber P21W (offset pins)
