In many (all?) U. S. states, your headlights must be functional at all times. IOW, if you have an obviously non-functioning headlight, you can be pulled over at noon on the summer solstice. Don't plan on being out after dark? Many states require you have lights on in the rain. Or that matter, can you guarantee you won't be caught out after dark?
So, in summary, by the law of many states the Tesla would be unusable for that year.
