Before I had a car with automatic daytime running lights (05 Corolla), I
routinely turned on my headlights during the day. DRLs are mandatory in
Canada and many other countries. Motorcyclists keep their headlights on
during the day to enhance visibility. The "camouflage" theory is faulty.

I can speak from experience that no matter how bright the lights
are on a motorcycle (day OR night), most people just don't see them.
Observation is object based and most drivers are looking for cars,
not bikes. You tend not to see what you aren't looking for.

But the camouflage theory is based on what the background is. If the
background is a brightly lit blue sky, then lights can be used to
camouflage an object on a hill (or an aircraft) becasue the lights
are reducing hte contrast between the bright sky and the silhouette
of the object against the background. I've seen this demonstrated
on one of them discovery-like channels.
