A trawler changes from a tricolour light to an all-round green light when it is engaged in fishing activities at night or in restricted visibility. This change signifies that the vessel is not under command and is actively fishing. The specific year of this regulation may vary by country and maritime authority, but the general practice has been in place under international maritime regulations for many years. Always consult the latest local maritime regulations for precise requirements.
