[Gage]

Installing fog lights on base model cars is not illegal. Below is an introduction to the functions and classifications of fog lights: Functions of Fog Lights: The purpose of fog lights is to make the vehicle visible to others in foggy or rainy conditions where visibility is significantly affected by weather. Therefore, fog light sources need to have strong penetration. Most vehicles use halogen fog lights, while LED fog lights are a more advanced option. Classifications of Fog Lights: Fog light switches generally have three positions: the 0 position is off, the first position controls the front fog lights, and the second position controls the rear fog lights. When set to the first position, the front fog lights are on; when set to the second position, both front and rear fog lights work together.
