Fitting is easy.
Open the bonnet, along the top of the grill are a few clips, push these gently with a screwdriver and the top will pop out. Then look carefully along the bottom of the headlight and there are a couple other clips. You can angle a screwdriver in and push these.
Now that's off you'll see four 8mm bolts on the headlight, one in each "corner".
Disconnect the headlamp wiring and remove the headlamp. Fit the new one back in.
