What is the standard for adjusting car headlight height?

[LeEvangeline]

Car headlight height adjustment standards are as follows: When adjusting the lights, do not use a wall. Drive the car onto a flat road, adjust the low beam points to coincide at a distance of 30 meters, and adjust the high beam points to be parallel to the ground. Walls are used to adjust the parallelism of the two high beam points. Below are the characteristics of car headlights: 1. High color temperature, with a bluish light color. K is the indicator of color temperature; ordinary halogen lights typically have a color temperature below 3000K. Xenon lights generally start at 4500K, and 7000K is quite common. Higher K numbers are generally closer to daylight and more easily accepted. 2. High brightness. Note that color temperature and brightness are fundamentally different concepts. Xenon lights are bright not because of their high color temperature but because of their high brightness. The unit of brightness is lumens, and the lumen output of xenon lights is generally three times that of ordinary halogen lights. 3. Low energy consumption and long lifespan. Other features include low energy consumption and long lifespan.
