Abstract
A trailer light assembly for use on boat trailers, which assembly is capable of maintaining a light fixture component of the assembly at such a height that the light fixture is not brought into contact with the water when the trailer is being used to launch or retrieve a boat. Maintenance of the desirable height is achieved by having the light fixture move upward or away from the water in response to a flotation device which is attached to the light fixture. The trailer light assembly may also feature a double-acting pivot point which will allow the flotation device to survive lateral forces thereon.
