Rear Lights - Separating the lens from the Body?

[Wilko58]

Hi,
Does anybody know how to separate the lens from the body of the Z3 rear lights (pre-facelift) please. I know there is a tiny screw on one end and a locking tab on the other but hard to tell if there are any tabs along the edge and if any glue has been used.
Thanks

Dont know how to seperate them but if you break them i have a spares you can have.

Cheers but breaking them isn't an option as they have been treated to a special coating (long story but it was applied to used lights with knackered gaskets)
