Speaking from experience, I wouldn't advise doing it. You literally have to take apart your headlights and melt off the glue to separate the lens from the assembly. The newer model 2003 headlights are almost impossible to take apart since BMW started using a new epoxy sealant. They make it sound easy but it's not. You can never be sure the headlights are sealed properly again and especially in Alberta, you will definately have condensation problems like I did. Finally I ended up buying a set of new headlights. Just my 2 cents...
