No. Lighthouses are not lit in daylight hours, because a lighthouse light is like a giant magnifying glass made up of usually hundreds of prisms. If the light was on in daylight hours the magnified beam of light is capable of focusing the sunlight just like you can do with a hand-held magnifying glass. This laser beam of light could easily ignite dry vegetation as the light sweeps over the land.

What is the cause of longer daylight hours on Earth?
Periods of daylight longer than 12.1 hours can happen only in one hemisphere at a time. It happens only while the hemisphere is tilted toward the sun. The maximum time between sunrise and sunset depends on the latitude of the observer. Along the equator the daylight period is 12.1 hours every day of every year. At each of the north and south poles there is one sunrise and one sunset each year. Only places north of the Arctic Circle and south of the Antarctic Circle can have at least one day per year when the sun is visible throughout the entire 24-hour period. That is because the 23.44-degree tilt of the Earth's rotational axis causes the 23.44 degrees of latitude closest to the pole to be completely lit by the sun at the moment of the summer solstice.
