Removing Highbeam insert

[brendanm]

Can anyone brief me on the best way to remove the highbeam insert so that I can replace the lens on it. I understand the chrome ring simply pops out, but I was told the best way to replace the lens is to remove the unit entirely so that clamps can be applied to the unit when the new lens is glued into place.

Any advise would be appreciated. I don't have a Bentley manual, although the OEM part website has got some good diagrams. Do I need to remove the grill etc.. or will the highbeam insert come out without that having to be done?

Any suggestions or help would be appreciated.
