I have a Halogen (victory oem) that has a broken lense. Any tips in separating it for the back/base that holds the bulbs? I see there is a sealant joining the two pieces and what I though was a metal ring. It is not a metal ring. It is silver painted glass. So I'm kind of perplexed. I'm sure I could break that stip of silver glass and separate the lense for the base. Then comes the question of separating the donor lense to replace the broken one on the halogen. Has anyone done this?
