What does the bridge overhead switch activate?

The bridge overhead switch is primarily intended to activate navigation lights and color staff lights. Navigation lights are essential for the safe operation of a vessel, ensuring that it is visible to others, especially during night operations or in restricted visibility conditions. Color staff lights are used to display the vessel's status or information, relevant in signaling various messages or conditions to other vessels or for operational needs.

This function is crucial for maintaining safety at sea, as proper signaling helps prevent collisions and ensures that the vessel's intentions are communicated clearly to other mariners. The inclusion of navigation and color staff lights under the bridge overhead switch underscores their importance in the overall operational readiness and safety protocols of the vessel.
