I'd say no, having somehow traversed France without any headlights! Doesn't seem to be a big deal ... until you get stopped and then they'll pick it up. The easist thing to do is take the deflectors you can stick over the lights. Even better, take some PVC tape with you and stick some in the right corner as a token gesture. This should be better than nothing at all should you be so unfortunate as to get stopped.
