Why are fog lights white now?

[OAmy]

This situation is indeed the case, especially when the surface of the car's fog lights appears white, but the actual bulb inside is orange, so it still emits yellow light when lit. More relevant information is as follows: 1. The function of fog lights is: to improve illumination in unclear road conditions ahead, providing a high-intensity scattered light source that penetrates dense fog, serving to alert oncoming drivers; in environments with low visibility such as fog, snow, or rain, to make the vehicle visible to other road participants behind. 2. Precautions for using car fog lights are: when visibility is below 100 meters, fog lights must be turned on and speed should be reduced; when visibility is below 30 meters, fog lights should be turned on, the vehicle should be pulled over, and hazard warning lights should be activated; in weather conditions with rain, fog, snow, or dust, fog lights should be turned on and speed should be reduced, but double flashing lights should not be used.
