The haynes manual says

"On early models, reach up behind the front wing, squeeze the plastic tabs together
and push out the light. On later models, turn the light anti-clockwise and withdraw it from
the front wing"

its listed as fairly easy but I just can't see how to get inside the wing. I've looked under the bonnet and under the wheel arch but I can't seem to get near the amber indicator light on the side of the car.

Anyone know, remember how to do this? Or am I meant to be unbolting things first to get at the back of the light? Thanks.
