I just watched this. I wouldn't bother.
The basic premise makes no sense to me. Even if by some strange happenstance snow covered your car lights completely, sealing the light in, and wasn't melted off by the lights or jiggled off by the motion you would have no headlights and would notice immediately that you couldn't see and rectify that before driving off. You wouldn't drive around clueless, thinking your lights were visible.
