What color is a special flashing light?

The special flashing light is typically yellow. This color is used primarily to indicate caution and is designed to alert other vessels or individuals of a potential hazard or special situation. In maritime contexts, yellow flashing lights are often associated with vessels that may be engaged in towing, dredging, or other activities that necessitate special attention from other vessels.

The choice of yellow serves a distinct purpose in terms of visibility and recognition, making it clear that the vessel may present a non-standard or hazardous situation requiring caution. This color choice helps ensure that other mariners are aware of the special operational status of the vessel.
