You installed a light because you have common sense.
My favorite part is, the law prohibiting the use of spot/docking lights while underway.
Granted, a fixed light on the bow of a boat doesn't do much good pointing toward the sky at night but there are self leveling style lights that maintain a beam horizontal to the water, no matter the angle of the bow.
ummm a bow angle within reason I should say. Given the doorknobs who have no idea of properly loading a boat and their boat moves through the water at a 75 degree angle. 😋
