the UNDOUBTEDLY CORRECT answer:

(if the current understanding of the universe is undoubtedly correct)

Yes

no matter what speed you are travelling at, the speed of light is constant relative to your motion.

ie the light still travels away from you at the speed of light, even though you are travelling at the speed of light.

... that's what relativity is all about


Hence the lights would light the way ahead of you... (from your perspective at least).


Mind you, travelling at about 670 million miles per hour but only lighting the road a few hundred metres ahead might not be much use after all...
