A lot of varibles are in play. On average, your headlights will produce more than 7.5 lux (lumens), but that varies with distance from the bulbs. The type of bulbs also comes into play as a variable. So, why not try it and see?
Frankly, I can't imagine a more boring video than watching lighted pavement going by over an extended period of time.
Nevertheless - it can be a fun experiment. Do it!
