No, headlights are only required to be turned on in dark and rain. In the state of WA, your car is to have two forward-facing front headlights. Though the law does not specify that they must work, I assume it is implied that word "headlight" means it will produce light at any given time.

Even aside from confusing the requirement for activated headlights with that for operable ones:

> Headlights are only required in dark and rain

...and in tunnels and in designated “daylight headlight areas” (often forested areas that are typically overshadowed); there are lots of places that cannot be accessed conveniently without crossing such a stretch.

> times when police aren't out trawling for violations to meet quota.

Even aside from th mistaken idea that times other than heightened enforcement (whether quota driven or otherwise) are safe from ticketing, there are lots of heightened enforcement times that can happen in dark and rain; and they are often times that people are likely to wait to to drive—particular holiday periods, for instance.
