Also no experience with those, but as an alternate thought, are those LED?
Those are sometimes made more as a one-piece deal and may be put together a bit different?
Any chance you can reach or see the backside? Not some small nuts on studs holding it all on the body?
As another thought, one might try squeezing along the sides to see if the lens might just snap in with small lugs??? Doesn't really seem right for an outside light, though!
I did a check of the parts catalog hoping for info to search for a picture but did not come up with anything except it is a "plastic bezel".
I guess that lets you call it the right name while muttering bad words?
