1989 Ford Bronco Headlight not bright

Hi, need an body shop or experience mechanics help, a diagram how to remove headlight lens for an 1989 Bronco II, 6 cylinder, 5 speed, 4 wheel drive. I need to clean the inside lens to make headlights more brighter, can't use a lens cleaner on them they are textured. If cleaning the inside lens doesn't work will buy new lens covers, but need a diagram to show how to remove them properly. Thanks Denise
