Are all car LED headlights higher on the right and lower on the left?

Car LED headlights are all higher on the right and lower on the left. In our country, vehicles are left-hand drive, so the left-side light is positioned lower to avoid causing light pollution, glare, or dazzling effects to oncoming vehicles and pedestrians, which could affect their safe driving. The right-side light is higher because, according to national standards, all road signs and markers are located on the right side of the road. This positioning helps drivers clearly see road signs without obstructing the view of oncoming drivers. Advantages of car LED headlights: Compact size: LEDs are essentially small chips encapsulated in epoxy resin, making them very small and lightweight. Low power consumption: Typically, LEDs operate at a voltage of 2 to 3.6V and a current of 0.02 to 0.03A, resulting in power consumption not exceeding 0.1W. Eco-friendly: LEDs are made from non-toxic materials, unlike fluorescent lamps that contain mercury and can cause pollution. Additionally, LEDs are recyclable. Durable: LEDs are fully encapsulated in epoxy resin, making them more robust than traditional bulbs and fluorescent tubes. There are no loose parts inside the lamp, which makes LEDs less prone to damage. Types of car headlights: There are three types: halogen lamps, xenon lamps, and LED lamps. Halogen lamps are the standard bulbs installed in cars at the factory, typically with a power rating of 55W, representing the first generation of car headlights. Xenon lamps are the second generation, and LED headlights are the third and latest generation of car headlights.
I've noticed that most vehicle headlights are indeed designed with the right side slightly higher. This is primarily to avoid dazzling oncoming drivers, especially during encounters. The left-side light is set lower so it doesn't shine directly into the eyes of drivers in the opposite lane. However, the specific height difference may vary slightly depending on the vehicle model and regulations – for instance, US-spec cars might have less disparity between left and right, while European-spec vehicles show more pronounced differences. When I replaced my LED bulbs, I found they automatically adjust to the correct angle when properly installed. If you notice both sides at the same height, that's actually a sign to check for installation issues or misaligned lamp sockets. While driving, observe the light cutoff pattern – a flat left side with an upward slope on the right generally indicates proper compliance with this design principle.
