Hey gang, I have an older 6P head that appears to not have a screw in bezel and instead has the lens glued in place or so it seems. It appears to be a plastic lens and it has a pretty bad haze. Another 6P I have has a crystal clear glass lens, with a screw in bezel ring. Question is, can I replace the lens on the light on the right, and if so what do I want and where do I get it?
