So a light that illuminates nothing is more effective than a light that illuminates something, in the fog.
I get it now...
Good for us that the factory fog lights illuminate nothing, because it keeps it from getting reflected back at us in the fog!
I think you would see even better in the fog if you shut off the headlights, right?
