D(AL), there is in fact a snap ring that is holding the lens in the chrome light frame. The snap ring can be removed by carefully using a small blade straight screwdriver. The ring is almost hidden inside the chrome ring. A word of caution, be sure to have someone helping you, or place a thick cushioning cloth like a blanket underneath the light fixture when you remove the lens. When it does come out of the frame it is in, it is alsmost impossible to catch it before it falls to the floor narrow and breaks the lens! Then there are two screws holding the light frame itself on the wooden supports in the top of the car.I hope this will help you! Tom Byrd
