Can these headlights be opened up?

Hi all.

 

I was wondering if anyone knows if these headlights can be split open, i.e. the glass removed from the reflector without damage? 

I seen modern ones can be opened using a heat gun to warm the glue. I'm assuming these are glued together?

A friend is doing a project and these size lights are perfect, but, needs to gain access to the insides and doesn't want to spend the money on them only to break them.

 

Cheers all
