A searchlight (also referred to as a spotlight) is a piece of apparatus that combines a powerful light source with a mirrored reflector in order to project a powerful beam of light of approximately parallel rays of light in the direction that the user needs to see in. A common use for them is to search for people who have fallen overboard a ship at sea.

Why isn't the corona visible during partial or annular solar eclipses?
The corona of the Sun isn't very bright; compared to the Sun itself, it is almost black. So when the Sun itself is visible, we cannot see the corona because all we can see is the Sun. It would be like trying to see the flame of a candle right next to a searchlight; all you would see would be the searchlight. We can only see the Sun's corona when the light from the Sun itself is blocked - as in a total solar eclipse. There are also specialized instruments called "coronagraphs" that block out the light from the Sun but allow the coronal light to come in.
