Rear offside reflector lamp in bumper

[SMH HS phev]

Hello does anyone have an easy way to remove this light fitting? It is held on with 3-4 screws but some do not seem very accessible from underneath the car. Thank you.

If you read the user manual it say you need to remove the back bumper. Not done this but if you can get your hand up to the light then find the wires to the bulb holder it turns one and comes out according to the book.
