When must you have your boat lights on?

Boat lights must be turned on during periods of low visibility, such as at night, during dawn or dusk, and in adverse weather conditions like fog or heavy rain. It's essential to display the appropriate navigation lights as required by maritime regulations to ensure safe passage and visibility to other vessels. Additionally, if you’re anchored or moored in a busy area, it's advisable to keep your lights on to alert other boats of your presence.
