Is It Normal for Low Beam Lights to Be Uneven in Height?

It is normal for low beam lights to be uneven in height. The left-side light is set lower to avoid dazzling oncoming drivers while still ensuring clear visibility of the road ahead. Low beam lights are designed for close-range illumination, featuring a wide coverage area but short projection distance. Vehicle lighting includes: 1. Turn signals: Indicate turning intentions to other drivers and pedestrians; 2. Headlights: Comprise low beams and high beams for road illumination; 3. Fog lights: Used in foggy conditions for better visibility; 4. Reverse lights: Alert pedestrians and vehicles behind when reversing; 5. Brake lights: Warn following vehicles of deceleration.
I've noticed many car owners asking about uneven low beam headlight height, which is actually not normal. Car headlights should be at the same height on both sides to ensure proper nighttime visibility and safety for others. Possible causes include burnt-out bulbs, loose lamp sockets, or misaligned adjustment screws. When I encountered this issue myself, I first checked if the bulbs were the same model - sometimes using bulbs of different sizes can cause unevenness. Additionally, poor road conditions or vehicle vibrations may cause bracket displacement. I recommend getting them professionally adjusted at a repair shop with proper tools. Otherwise, prolonged use may lead to difficulty seeing roadside signs or increased accident risks, especially in mountainous areas or winding roads - never take this lightly.
