From memory the headlight unit is attached to the front cowel and can be removed complete by removing maybe 4 or 6 screws that holds it all to the main stay / frame.
All this can be done after removing the two side panels inner clock surround and screen mount.
Also, depending on what crash bars you have , they may need to be removed in order to remove your side panels.
While it's all apart, you may want to take the opportunity to clean up and paint the main frame / stay as they tend to rust.
