KX2 plastic dome re-attachment?

[blueo8]

This little dome popped off of my flashlight head. How or can I re-attach it?

CAREFULLY

I don't see any glue residue in the picture so my first guess is it's a press fit. I'd try that first unless you see glue residue which makes things harder

I actually just did this. It seems like it is staying but I didn't know if it needed adhesive to stay. My searching seemed to lead to Norland 61. I hope the dry fit is all I need.
