Yes, in Iceland, 'Ökuljós' (running lights) are mandatory for all vehicles 24 hours a day, all year round, regardless of weather conditions or daylight.
High beams should be used on unlit roads when there is no risk of dazzling other drivers or cyclists. You must dim your high beams when approaching oncoming traffic or when following a vehicle ahead.
Front and rear fog lights ('Þokuljós') should only be used when visibility is severely reduced due to fog, heavy rain, or snowfall. They must be switched off when visibility improves or when they could dazzle other drivers.
Indicators are vital for communicating your intentions. Use them well in advance when changing lanes, turning, or exiting roundabouts, especially on busy roads and highways like Reykjanesbraut, to ensure smooth and safe traffic flow.
