LED what's special about the ship lights? What lamps does the general ship need? Where's the submarine?
LED has a large brightness and saves power, and the volume can also be made smaller. The ship must have a beacon light, which is only to be detected by the front, side and side (two or less)
Lifting his part will have a warning indication lamp, and lighting, a small fishing general external headlight. Submarine is generally not lighting on the water, but there will be a headlight and rotatable searchlight is used
