Tail light lens removal question

I have the stock tail light of renegade can am 1000 (in the picture) I would like to replace it with the LED 3" round light (also in the picture). Can someone tell me how to remove the stock light out (+ the lens)from the bezel without breaking the casing?
Is this stock light replaceable or fixed? Can the lens be extracted out or pry out? do I need to use a dremel to remove this out?

Thanks for any help and advice.
