This is what you'll be left with.
Using a 10mm hex or Torx30, remove the inner bolt.
Look at the front edge of the arch panel and remove these 2 bolts also.
This disconnects it from the body and the arch panel.
On the edge of the scuttle panel, just behind the headlight is a foam piece...
...that can be pulled out to reveal...
...the clip holding the headlight in place. Reach behind and push the clip up with a finger...
...and pull the headlight out.
Disconnect any electrical connections and this will allow you to remove the light from the car.
If you are fitting a replacement headlight, don't forget to swap this bracket over.
