Steamer light

Machine vehicle in motion

With steaming light , historically also steamer lantern , in the maritime , the front or only colloquially masthead light referred. It is guided by machine vehicles in motion in addition to the lights that sailing vehicles already have to guide (side and stern lights). It therefore differentiates between motorized watercraft and sailors who are privileged on many bodies of water.

The steamer light is white and encompasses an angle of 225 ° shining forward, i.e. 22.5 ° more astern from port side than abeam across the right-hand alignment (direction of the bow) to starboard 22.5 ° more astern than abeam. This is the same area that the red and green sidelights cover together.

The steamer light must be amidships and at least one meter higher than the sidelights. Vehicles over 50 m in length require a second masthead light on sea waterways, but this is usually not referred to as a steamer light.

These provisions are given by the collision avoidance rules.
