seperating headlight lens by baking?

Hey guys was just wondering is anybody separated their headlight or tail light lenses by baking them in the oven. I heard that if you bake them around 180 degrees for 10 minutes the glue should be soft enough to be able to separate the lens from the housing. has anybody tried this any info would be appreciated. I’m planning on putting halo lights on my sportsman 800 2014.
