Bulb replacement of the High Intensity Rear Fog lights.
Why choose LED? I think all the bulbs should have been LED from the factory. Indicators certainly benefit from being replaced. The fog lights I don’t think make much difference. There is a reflector in the lamp unit, and so because the LED is in a slightly different position it makes little difference to the overall light output. Bulbs are white PY21W fitting.
Photo shows LED in the left lamp and original filament bulb in the right side.

A simple job, but the fact that the second side took half the time of the first means this might save someone else from going up the learning curve.
You have to remove the rear wheel arch liner and reach in to access the bulb holder. As I’m right-handed the right side of the car was easier than the left.
First remove the wheel. Take this opportunity to clean the caliper or you will get brake dust over your hands and clothing.

These are three of the four screws that retain the wheel arch liner. They are quite long, so make sure your screwdriver will fit.


There are also two pop fasteners beneath, pry them out to about 4 mm and then wiggle them free. Note the stones poking through the slots.


When the fixings are out there is a specially positioned nut on the caliper to hold the liner clear of your access

Take this opportunity to remove all the stones, twigs etc. that have gathered here.
