No need to remove wings; jacked up and wheel off should be sufficient.
As others have said, the brackets are a pig
See Cerealsurfers buying guide -
"Headlights
The front head-lights are VW Beetle lights and due to the mounting of the light housing can “jar” the lense against the wing. This results in the lense being pulled off the housing letting in water usually from the bottom of the lense area. You can easily spot it by misted lenses and a visible split in the rubber on the inside of the lense. Do not just replace the light housing.
If the cause is not fixed it will only happen again. "I like Taffmog's idea re. the Waxoyl; it should provide a little bit of
'slip' and allow the lamp to move slightly....
Final point; don't be tempted by aftermarket 'copy' parts - they are subtly different and you may have problems fitting.
I would recommend the Magneti Marelli versions.These are made by Automotive Lighting who were set up by Bosch and Magneti Marelli but are now fully owned by Magneti Marelli.
Have fun......
