Lightning

This section states that the level of lightning should be adequate enough so that the crew working on the bridge can perform all their tasks, during both day and night-time conditions. To achieve that, the section requires that the lighting is separated in different sections that can be switched on or off individually.

The section also requires that illumination of instruments, such as buttons and controls should be fully dimmable, or otherwise illuminated in a colour that does not compromise night vision, such as dark green or purple.

Additionally, it is required to have two separate electrical circuits provided for bridge lightning, as well as emergency lightning on the bridge and its entrance points.

Deck and superstructure light as well as navigation lights should be fully controllable from the bridge. Navigation lights are to be provided with an audible and visual alarm. For all navigation and indicator lamp control panels, a test alarm function should be provided.
