Are car headlights universal?

There are very few universal car headlights. Because each car company is different, the level of design, R&D and styling is different, which makes the headlights of each brand different. Because of the differences in the size of the front fender, cabin layout, hood shape, bumper shape, and headlight mounting bracket, the headlights of each brand are different. The most important point is the problem of parts supply and sales, which makes each car company not use the same headlights as other companies. Except for car companies that try their best to imitate other models.
