Hi all. Can anyone tell me what holds the bottom of the headlight . I have removed the top plate and the torx head screw down in the recess but I am still unable to remove the headlight. Thanks for any advice

Bumper off, I'm afraid.

Many thanks for this inspectorman. A complete explanation which is much more than I expected. More work than I hoped but at least I know exactly what I am doing. Thanks again. Graham

Just a couple more things inspectorman. Do you have a diagram showing the position of the wheelhouse fixings and is the lens removable from the light assy. once the light has been removed.Again, thank you for all of your invaluable advice and help. Graham

I've not seen removable lenses on a car headlight for decades. Here's the "wheelhouse" diagram. Just keep taking screws out until you can get it off.
