I have not separated them on a Gator but I have done it with others. I used a Exacto razor saw and a Dremel tool to cut along the seam where the parts are glued together. Then once they are apart you can clean them up and glue them back together with two party epoxy or silicone caulk. Before going through all that though I'd check the price for new light housings. New ones might be cheap enough (I can dream) that it's not worth the effort.
