the headlight blackouts don't really fall out (i've never had a problem with em when I had em), but the taillight blackouts are only held on by velcro. I'm thinking about removing my lenses and tinting them, but haven't gotten around to it
I know in most states, they're considered illegal since the rear reflectors on the car are no longer visible from 500' with ample light illuminating them.....check your local laws
