Headlights should not be used or their mode should be adjusted in the following situations: There is no need to turn on the headlights when the daylight is sufficient and there is no severe weather, but low beams should be turned on immediately when entering a tunnel or underground parking garage; On urban roads with street lighting at night, low beams should be used to avoid the glare hazard caused by high beams directly shining on oncoming vehicles or the rearview mirrors of preceding vehicles. High beams can be used in suburban areas without street lights or on highways, but they must be switched to low beams when within 150 meters of an oncoming vehicle; In low-visibility conditions such as foggy or rainy weather, fog lights and low beams should be turned on. When visibility drops below 100 meters, hazard warning flashers may be additionally activated; High beams are prohibited when following another vehicle at close range in the same direction. When overtaking, drivers should flash their headlights (alternate between high and low beams) to signal the preceding vehicle; If the vehicle is equipped with non-SIRIM certified LED or HID headlights, they must be replaced with compliant ones to avoid a 300-ringgit fine. For instance, turn signals should be activated at least 3 seconds before changing lanes or making turns, and hazard lights should be used when temporarily parked. Improper use of high beams or fog lights may disrupt others' judgment and lead to accidents.
