The use of car headlights should be adjusted appropriately based on specific road conditions and regulatory requirements. When driving at night on unlit roads, high beams should be activated to enhance visibility, but must be switched to low beams at least 150 meters before encountering oncoming traffic to avoid glare. In urban areas with street lighting, only low beams are necessary. Headlights and fog lights must be immediately activated when entering tunnels or during fog with visibility below 100 meters. Hazard warning lights should only be used during vehicle breakdowns or emergency stops. As a critical communication method, light flashing follows standardized protocols: a single flash signals overtaking intention or green light departure prompt; two consecutive flashes alert oncoming drivers to deactivate high beams or correct lane deviation; three rapid flashes serve as an emergency warning for rear vehicles to avoid obstacles. Under 2026 regulations, improper use of high beams or hazard lights will incur a RM100-200 fine and 1 demerit point. Note that light control locations may vary across vehicle models, requiring familiarity with each vehicle's interface.
