How do you take off the headlight lens on a 98 Toyota corolla?

Actually.. to take the headlight lens apart, put the Oven on 200, put the headlight assembly in oven for a few minutes at a time, as the headlight assy heats up, the adhesive will loosen up making it easy to remove the lens. For a demonstration, go to YouTube and type in "How to remove headlight lens from assembly"
