What is the adjustment method for xenon headlight focus?

Xenon headlight focus adjustment method: Remove the screws of the xenon headlight assembly, then detach the bulb clip. After turning on the headlight, move the bulb upward and check against a wall to ensure the focal point is slightly above the cutoff line. Xenon headlights have high brightness, measured in lumens—the higher the lumen value, the brighter the light. Xenon lamps, also known as high-intensity discharge (HID) lamps, are metal halide lamps. They work by filling an ultraviolet-resistant quartz glass tube with various chemical gases, including xenon and other inert gases. A ballast then boosts the vehicle's 12-volt power supply to 23,000 volts instantaneously. Under this high voltage, xenon gas is ionized, creating a light source between the two electrodes.
