removing rally lens from bezel

You'll need to work around rather than seperate one at a time. In many cases there will be a tiny white donut like piece that comes off. You could save those for reuse or find a little donor ABS material for reattach.
Reach under the bezel and gently pull on the center cones to remove those first.
then remove the metal frames, and finally the lenses.
Although the large lenses look the same they are not interchangable. Their mounting ears are in different locations.
You cant be too careful. The slightest touch against the lens with a hot soldering iron will scar it. Good luck
