What is the required color temperature range for car headlights?

The color temperature should be between 3500K and 5000K, with 4300K generally providing the best lighting effect. Here is some relevant information about color temperature: 1. Color temperature is the most common indicator of the spectral quality of a light source. It is defined based on an absolute black body. When the radiation of a light source in the visible range is identical to that of an absolute black body, the temperature of the black body is referred to as the color temperature of the light source. 2. The higher the color temperature, the cooler and whiter the light appears; conversely, the lower the color temperature, the warmer and yellower the light appears. Due to differences in color temperature, the color of the light also varies. For example, at 4300K, the light appears white with a slight yellow tint; at 6000K, the color is white and close to natural light; at 10000K, the light takes on a light blue hue. This shows that as the color temperature gradually increases, the color of the light shifts toward cooler tones, commonly referred to as cool light.
